Machine learning (ML) algorithms analyze data to uncover patterns and generate insights. Based on their training approach and objectives, they can be categorized into four main types: Supervised learning uses labeled data (input features + corresponding output labels) to train models. The algorithm learns to map inputs to outputs, making predictions on new, unseen data. It’s divided into three key tasks: Classification: Predicts discrete categories (e.g., spam detection). Regression: Predicts continuous values (e.g., house prices). Forecasting: Predicts future trends (e.g., weather forecasts). Example: Predicting stock prices or customer churn. Unsupervised learning works with unlabeled data, identifying hidden structures or patterns. Since there’s no "correct answer" provided during training, the algorithm explores similarities/differences autonomously. Common techniques include: Clustering: Groups similar data points (e.g., customer segmentation). Dimensionality Reduction: Simplifies data while preserving key features (e.g., PCA for visualization). Example: Market basket analysis or anomaly detection. A hybrid approach combining small amounts of labeled data with large unlabeled datasets. This is cost-effective when labeling data is expensive or time-consuming. Applications: Speech recognition, medical image analysis. RL trains an agent to make decisions via trial and error, using feedback from rewards/penalties. The agent learns optimal strategies by interacting with an environment. Use Cases: Game AI (e.g., AlphaGo), robotics, autonomous vehicles.  ( 3 min )

You’ve added startSession() and startTransaction() to your Mongoose code, only to be greeted with: Transaction numbers are only allowed on a replica set member or mongos If you’re running MongoDB in a standalone Docker container, transactions simply won’t fire — because MongoDB requires a replica set (even if it’s just one node) to support transactions. Let’s break this down from the ground up — no prior MongoDB knowledge assumed. A replica set is a group of MongoDB processes that maintain the same data set. One member is the primary, which receives all write operations. The others are secondaries that replicate (copy) data from the primary in real time. Primary: accepts reads (depending on your read preference) and all writes. Secondary: copies data from primary; can optionally serve re…  ( 6 min )

I've been dying to find a reliable lightweight local model to pair with my agent Goose so I can run everything locally and keep my work private. Every time a new local model drops, I think "is this it? are we finally here?" and each time, I'm disappointed. Today was no different 😔 Ollama's announcement of devstral stopped me in my tracks. They specifically touted that the Minstral AI model was "designed to excel at agentic coding tasks". When testing models for agentic capabilities, I run through a sequence of prompts. Here's how devstral performed. Note that I lowered the temperature of devstral to 0.2, which is better for exact tasks like tool calls.

Then a teammate pings me to review their PR. Their project also runs on localhost:3000. Fortunately, modern frameworks are smart enough to automatically bump to ports 3001 or 3002. Before I know it, 3003, 3004, and 3005 are running too, and my laptop sounds like it’s about to take off as it crawls under the weight of too many processes.

The days when adding dynamism to a web page was limited to a few lines of jQuery are long gone. Modern web applications are complex ecosystems, interconnected with APIs, databases, and external services. This inherent complexity brings with it a constant and often underestimated challenge: error handling. In my years of experience, I’ve seen how poor error handling can crush the user experience (UX), hinder the traceability of problems, and not less important, affect the developer experience (DX). What happens when your application can't get data from the server? The possibilities are endless: an internal server error (5xx)? An authorization problem (4xx)? Perhaps your application expected a nested object like foo.bar, but bar never arrived in the response? Or a user encountered an unexpec…  ( 16 min )

Just a decade ago, web development was straightforward: all rendering was done server-side, meaning each click on a hyperlink loaded a new page with fully-rendered HTML. This thin client setup allowed browsers to seamlessly handle navigation and made the system ideally suited for search engine indexing. As the internet evolved, so did user expectations. Websites were no longer just static pages of information, but needed to be interactive with features such as real-time updates and dynamic content. This demand led to the creation of Single Page Applications (SPA), where the backend transformed into an API serving data, and the frontend handled rendering and interactions. In mid-2000s Gmail revolutionized web development by becoming the first true SPA project. Its seamless user experience i…  ( 6 min )

🔍 Introduction: Why You Need This Ever looked at your Git history and seen a mess of “WIP”, “fix typo”, and “oops” commits? You’re not alone. Most developers use git merge and live with cluttered histories. But top engineers at FAANG companies rely on git rebase -i (interactive rebase) to keep their commit logs clean, logical, and professional. In this guide, you’ll get: Interactive rebase lets you rewrite, reorder, or combine commits before sharing them. Here’s how to use it: git rebase -i HEAD~3 # Edit the last 3 commits Problem: You have 5 messy commits: # Commit list - Add login button (WIP) - Fix typo - Refactor auth logic - Fix lint error - Update README git rebase -i HEAD~5 An editor window will open showing the following. Squash “Fix typo” and “Fix lint error” into “Refactor auth logic.” Reword “Add login button (WIP)” to “Implement login button.” Drop unnecessary commits. For the next window, enter the reworded commit “Implement login button” and hit save. Result: A clean, logical history. # Commit list - Refactor auth logic - Implement login button - Update README --autosquash Manually marking commits for fixup is tedious. Instead, use --autosquash to automate it: 1. Mark commits as fixes: git commit --fixup=COMMIT_HASH 2. Run rebase with --autosquash: git rebase --autosquash HEAD~N # Accidentally left a small change from committing? Fix it: git add . git commit --fixup=abcd123 # commitSHA of the original commit git rebase --autosquash abcd123 # No manual editing! Why FAANG engineers love this: Saves hours of manual rebasing. Keeps history clean without effort. ⚠️ Golden Rule: Never rebase pushed commits (unless you’re alone on the branch). Already pushed an incorrect rebase to repo. No worries, use this. git reflog # Find the commitSHA for pre-state git reset --hard commitSHA [alias] ri = rebase -i ras = rebase -i --autosquash Up Next in the Series: Day 2: git cherry-pick—The Surgical Way to Move Commits.  ( 4 min )

I’m a frontend developer who has worked with Angular and React for the past few years. Both frameworks have taught me a lot, but React in particular has dominated my recent experience. It’s popular, flexible, and powerful — no doubt about that. But despite its upsides, working with React in real-world production apps slowly pushed me to a breaking point. React often felt… messy. Even though React gives you freedom, that same freedom can become a burden, especially as your project grows. Every team ends up inventing their own structure, folder naming conventions, and state management preferences, and you’re left stitching everything together with dozens of third-party libraries.

Clean code isn't always fast code. While abstractions like LINQ, interfaces, or dependency injection make our code cleaner and more maintainable, they can introduce runtime overhead. And in performance-critical paths, those costs add up quickly. In this article, we'll walk through how common .NET abstractions can degrade performance, explore when to use them with care, and share techniques to avoid unnecessary overhead. LINQ is incredibly expressive, but it's not always the most efficient — especially in tight loops or "hot paths." var filtered = data.Where(x => x.IsActive).ToList(); ` While flexible, LINQ's deferred execution model can lead to hidden costs. The .ToList() call here forces immediate materialisation, introducing new allocations for the list and potentially temporary iterat…  ( 5 min )

The platform gave us the ability to scale from a small inventory to several thousand SKUs with product combinations across sizes, fabrics, and colors—without major dev overhead. One of the trickiest parts of building the site was how to organize products by cut, fabric, and seasonal style. Our catalog isn’t just big—it’s complex. For instance, our Bottomwear collection includes ev…  ( 4 min )

When you use a smart AI assistant or agent—whether it’s helping write code, answer questions, or run a workflow—there’s a lot going on behind the scenes. One key challenge is how to talk to the language model clearly and consistently. That’s where Model Context Protocol (MCP) comes in. Model Context Protocol (MCP) is a simple but powerful idea: it’s a standard way for an AI agent to organize and format the prompt it sends to a language model. You can think of it like a checklist or recipe. Instead of throwing together bits of context in random ways, MCP tells the agent what information to include, in what order, and how to label it. Language models are smart, but they’re also sensitive to how you talk to them. If your prompt is messy, missing key details, or mixes things up, the model migh…  ( 4 min )

Introduction In modern software development, APIs and distributed systems must handle failures gracefully. Network issues, timeouts, and client retries can lead to duplicate requests, causing unintended side effects like double charges, duplicate orders, or inconsistent data. Idempotency solves this problem by ensuring that performing the same operation multiple times has the same effect as executing it once. This article explores idempotency, its importance, real-world examples, and best practices for implementation. What is Idempotency? An operation is idempotent if repeating it does not change the result beyond the initial execution. Key Characteristics Same Request → Same Effect: Multiple identical requests produce the same outcome as a single request. Safe Retries: Cli…  ( 4 min )

I've been working on a karaoke game idea in Python for a bit now and I stumbled upon a small problem: The scoring system. As of now, I am able to generate an isolated vocal track and also generate the pitches for this track. So the next step, naturally, would be to figure out how to get the pitches from a live audio input stream. But given the live audio stream, I would have to be able to compare these pitches live and return that result to the user in some sort of scoring system. Furthermore, the library that is used for determining the pitches in the audio takes a bit of time (using CREPE). It is fine for processing to take a long time when generating a reference track but in practice, there needs to be a faster way. Well, for now I will tinker with PyAudio for a bit and see what I can do.  ( 3 min )

Cloud data lakes help centralize massive volumes of structured and unstructured data. They support scalability, simplify data integration, and reduce storage costs. However, adopting a cloud data lake is not without its challenges. Without the right planning and oversight, it can become more of a liability than a strategic asset. Below are five key challenges organizations often face when working with cloud data lakes. Based on my experience at Bacancy, I have described each of the 5 challenges in detail that talk about what businesses may find tough to manage, when using a cloud data lake. One of the biggest risks with a cloud data lake is the gradual decline in data quality. When teams push raw data from multiple sources without a defined structure, the result is often a chaotic and unre…  ( 5 min )

When you’re building a full-stack app with a separate frontend and a Flask backend, the browser’s Same-Origin Policy will block your API calls unless you explicitly allow them. Cross-Origin Resource Sharing (CORS) is the protocol that lets you opt-in. In this guide we will cover two common ways to get it done in Flask. Flask lets you set response headers directly, so you can choose which endpoints get which CORS rules. If your frontend lives at https://myapp.com, you can allow it like this: from flask import Flask, request, jsonify, make_response app = Flask(__name__) @app.route("/api/hello") def hello(): resp = make_response(jsonify({"msg": "hi"})) # allow just one origin resp.headers["Access-Control-Allow-Origin"] = "https://myapp.com" return resp Whenever the browser …  ( 4 min )

Written by Kealan Parr✏️ This article explores how to pass functions and structured objects as parameters in TypeScript. It highlights use cases, syntax differences, and practical scenarios where each may be preferred, especially when working with function types, inheritance, excess property checks, and optional fields. In JavaScript, functions are considered first-class citizens, which means they can be handled like any other type of variable, including numbers, strings, and arrays. This allows functions to be passed into other functions, returned from functions, and assigned to variables for later use. This feature is heavily used in asynchronous code, where functions are often passed into asynchronous functions, often referred to as callbacks. But this can be tricky to use with TypeS…  ( 14 min )

🧠 Introduction Classical algorithms are already incredibly effective at solving many optimization problems, especially when the number of variables is in the low thousands. However, when scaling up to problems involving tens or hundreds of thousands of binary variables, classical solvers begin to falter due to the combinatorial explosion in the search space. Quantum computing offers a compelling alternative, not by brute force, but by exploring exponentially large solution spaces in parallel using quantum superposition and entanglement. One popular quantum algorithm for such problems is the Quantum Approximate Optimization Algorithm (QAOA) [3], a textbook example of a variational quantum algorithm (VQA). However, QAOA requires one qubit per binary variable, which becomes prohibitively r…  ( 8 min )

If you’ve ever delayed pushing to production because “it’s just too much right now,” you’re not alone. For small teams - especially startups and indie developers, deployment often becomes the most dreaded part of the workflow. Not because it’s hard, but because it’s messy, time-consuming, and filled with “extra stuff” like YAML files, CI/CD config, and infrastructure setup that feels disconnected from actual product building. So what if there was a simpler way? What if deploying your app was as easy as pushing code - and that was it?

📌 What is OFFSET? The OFFSET clause in PostgreSQL is used to skip a specific number of rows before starting to return rows from a query. It’s often used along with the LIMIT clause to implement pagination — a technique to fetch a small chunk of data at a time. 🔧 Syntax SELECT column1, column2 FROM table_name OFFSET number_of_rows_to_skip; Usually, it's paired with LIMIT like this: SELECT column1, column2 FROM table_name LIMIT page_size OFFSET number_of_rows_to_skip; 📊 Real-World Example Let’s say you have a table called students: id name grade 1 Alice A 2 Bob B 3 Charlie C 4 Diana B 5 Edward A Example 1: Simple OFFSET SELECT * FROM students OFFSET 2; Output: id name grade 3 Charlie C 4 Diana B 5 Edward A This query skips the first 2 rows and returns the rest. Example 2: LIMIT with OFFSET (Pagination) Let’s say you want to show 2 students per page: -- Page 1 -- Page 2 -- Page 3 This way, you only load a few rows at a time, which is better for performance and user experience. 🛠 When to Use OFFSET To implement pagination in web applications. To load large datasets incrementally. To skip over records during testing or debugging. ⚠️ Caveats Performance: Using large OFFSET values can slow down performance because PostgreSQL still scans through skipped rows internally. Duplicate or Missing Records: If the data changes between paginated queries (like inserts or deletes), you might get duplicates or miss some records. ✅ Pro Tip: For large datasets, consider using keyset pagination (e.g., with WHERE id > last_seen_id) for better performance. 📚 Summary OFFSET Skips N rows before fetching LIMIT Restricts number of rows returned Together, they form the backbone of pagination in SQL queries.  ( 3 min )

Browsers will often cache static assets to improve performance. This can cause issues when a new version of the application is deployed but the browser is still reading the old cached version. With cache busting, we append a hash to the static file names e.g vendor.js becomes vendor.437b51dcc2.js. When a deployment is made the hash changes e.g vendor.437b51dcc2.js may change to vendor.74t74t5tt.js. With cache validation enforced by the meta tags below, the browser will first check if the there is a new version of the file before using the cached versions. It will thus request for the new version of the file. (Add these to your src/index.html as Step 1) Step 2 var …  ( 5 min )

Arrays usually get all the love. They're easy to use, built into every language, and great for most tasks. But there’s another data structure that quietly powers a lot of efficient solutions: the linked list. It’s not about speed for direct access — it’s about flexibility, efficient insertions, and being the foundation for structures like stacks, queues, and even graphs. Let’s give it the spotlight it deserves. A linked list is a linear data structure made up of nodes. A value A reference (or pointer) to the next node A simple representation: [10] → [20] → [30] → null Unlike arrays, elements in a linked list are not stored in contiguous memory. This makes linked lists: More memory flexible Ideal for fast insertions and deletions Slower for direct access to elements by index Use a linked…  ( 5 min )

Problem While working on a project, I came across an interesting issue. Multiple TypeScript and bash scripts needed to read from or write to a shared file. Thus, the scripts needed the file path (directly or indirectly). The question is: if the file location changes, how should I structure the code such that only one file needs to be updated (and thus reduce the risk of missing updates in various scripts)? The Typescript scripts could import the file path in a utils.ts and use a getSharedFilePath function e.g. import { getSharedFilePath } from "utils"; const SHARED_PATH = getSharedFilePath(); BUT! What about the bash scripts?

🌱 “菜谱”“成品菜”与“菜谱册” 的比喻 类（Class） 就像“菜谱” 菜谱告诉你：这道菜要哪些食材、要哪些步骤。 在 Java 里，class User { … } 就是一份菜谱，规定了属性和方法。 对象（instance） 就像“做出来的一盘菜” 当你按照菜谱炒菜，你就得到了“成品菜”。 在 Java 里，new User() 就是按 User 这个菜谱“做”出了一个具体的 User 对象。 Class 就像“菜谱册”里一本特定的菜谱 你家里有一本菜谱册子（一本书），里面夹着很多菜谱。 如果你拿起“《宫保鸡丁》”这一页，那就是“Class”——表示“宫保鸡丁这个菜谱”。 你不做菜的时候，这一页不用动；要做菜时，你可以读它，看看食材和步骤，甚至还能标注“我改良了这道菜”——这类似于反射里看注解、改构造参数等。 // 1. 定义菜谱（类） public class User { private String name; public User() { } public void sayHi() { System.out.println("Hi, I'm " + name); } } // 2. 做出一盘菜（对象） User u = new User(); // 这就是“new User()”产生的实例 u.sayHi(); // 3. 拿到那页菜谱（Class） Class userClass = User.class; User.class：就是那个“菜谱册”里“User”这一页的对象，类型为 Class。 你可以用它做反射操作，比如： // 通过菜谱（Class）再做一盘菜 User u2 = userClass.getD…  ( 3 min )

SQL (Structured Query Language) is the foundation of interacting with relational databases. Whether you’re building a side project or working in a production environment, writing efficient and readable SQL can save you hours of debugging and optimization. In this post, I’ll share 5 practical tips to help you write smarter SQL—whether you’re using PostgreSQL, MySQL, or SQLite. 1. Be Specific with SELECT Bad: SELECT * FROM users; Better: SELECT id, name, email FROM users; 2.Use Table Aliases for Clarity Bad: SELECT * FROM orders o JOIN customers c ON o.customer_id = c.id; Cleaner: SELECT o.id AS order_id, c.name AS customer_name Good aliases make your queries easier to scan, especially in team environments or long queries. 3. Index Strategically Example: CREATE INDEX idx_users_email ON users(email); SELECT * FROM users WHERE email = 'user@example.com'; 4. Keep It DRY with Common Table Expressions (CTEs) Instead of nesting subqueries: SELECT name FROM ( Use a CTE: WITH user_counts AS ( 5. Use CASE for Conditional Logic SELECT name, This makes your logic explicit without post-processing in application code. N/B: SQL is simple on the surface, but powerful underneath. The more intentional you are with your queries, the better performance and maintainability you’ll get.  ( 4 min )

For the past couple of months, the concept of MCP has been booming. MCP (Model Context Protocol) was developed and released by the end of 2024 by Anthropic. It allows AI agents and LLMs to interact with third-party APIs in order to work with real data and allows them to make actions on your behalf. In the case of a Redis MCP, as you will see further in the blog, it means that you can search through your database using natural language. Now, to utilize MCP and allow it to interact with other APIs, you will need an MCP server that exposes tools for your agents to use. The big question is how to run your MCP servers without making life harder for your developers. Having everyone set up their own local server is tedious and invites all kinds of inconsistencies. Centralizing it as a shared serv…  ( 7 min )

Let’s uncover the layers of testing that silently fuel the world’s most reliable applications: Testing isn’t just about discovering defects — it's about ensuring confidence. It verifies business logic, validates user experience, and safeguards against regressions. Good testing builds trust — for both the team and the end-users. Waiting until development ends to test is outdated. Modern QA begins during planning, collaborating with developers and analysts to write better stories, define edge cases, and prepare smarter test data. Automation helps with speed, but it’s not a magic wand. Understanding what to automate (and what not to) is key. A balanced strategy combining manual, exploratory, and automated testing leads to optimal results. Today’s testers are not just script runners. They’re quality advocates, embedded in agile teams, contributing to design reviews, writing testable requirements, and driving continuous improvement. Stop counting just test cases and defect counts. Modern teams track defect leakage, test coverage gaps, and test debt — metrics that help assess not just quantity, but the impact and effectiveness of testing. Software testing isn’t a bottleneck — it’s a business enabler. The faster we test well, the faster we ship with confidence. 🚀  ( 3 min )

I. Executive Summary Apple's Siri, a pioneering voice assistant, has faced persistent user complaints and criticisms over the past decade, primarily stemming from its functional limitations. These shortcomings, including frequent misinterpretation of commands, shallow responses, and a notable failure to maintain conversational context, have led to widespread user frustration. This report posits that Siri's anthropomorphic design cues—its human-like voice, tone, and conversational interface—are not merely aesthetic choices but are, in fact, the fundamental cause of user misperceptions. By implicitly encouraging users to treat Siri as if it possesses genuine understanding or thought, these design elements create unrealistic expectations.

Building lasting habits isn’t about sudden, massive changes — it’s about small, consistent actions repeated every day. Here are some key points from 𝗔𝘁𝗼𝗺𝗶𝗰 𝗛𝗮𝗯𝗶𝘁𝘀 by James Clear, along with simple examples to help you apply them: 𝟭. 𝗧𝗿𝗮𝗰𝗸 𝗬𝗼𝘂𝗿 𝗛𝗮𝗯𝗶𝘁𝘀: Keep a simple log or calendar. For example, mark an “X” every day you meditate. Visual progress motivates you to keep going. 𝟮. 𝗡𝗲𝘃𝗲𝗿 𝗠𝗶𝘀𝘀 𝗧𝘄𝗶𝗰𝗲: Missing a day is okay, but don’t let it turn into two days. If you skip your workout once, commit to doing it the very next day. 𝟯. 𝗦𝘁𝗮𝗿𝘁 𝗦𝗺𝗮𝗹𝗹: Begin with tiny actions, like reading one page or doing 2 minutes of exercise. This makes habits easy to start and maintain. 𝟰. 𝗨𝘀𝗲 𝗩𝗶𝘀𝘂𝗮𝗹 𝗖𝘂𝗲𝘀: Place reminders in your environment. Lay out your workout clothes the night before to cue morning exercise. 𝟱. 𝗥𝗲𝘄𝗮𝗿𝗱 𝗬𝗼𝘂𝗿𝘀𝗲𝗹𝗳: Finish your habit with a small reward — like enjoying a cup of coffee after completing a task — to reinforce the behaviour. 𝟲. 𝗕𝘂𝗶𝗹𝗱 𝗜𝗱𝗲𝗻𝘁𝗶𝘁𝘆, 𝗡𝗼𝘁 𝗝𝘂𝘀𝘁 𝗢𝘂𝘁𝗰𝗼𝗺𝗲𝘀: Focus on becoming “the type of person who writes daily,” rather than just finishing a book.

SSH stands for Secure Shell. It is a cryptographic network protocol used to securely assess and manage remote computers over the Internet. You are expected to see the usage instructions like this PS C:\Users\USER> ssh If you did not see this, then you will have to install OpenSSH, which can be found in the settings of your Windows OS. Your identification has been saved in ozoSSh This signifies that the keys have been created. the file name with .pub”, • Now that you have created your droplet/server on Digital Ocean, the next thing is to copy the IP address and return to the PowerShell. • In PowerShell, you can then type; the file directory of the private key, i.e the file without the .pub suffix root@IP address of the remote server” This will prompt you to type in your passphrase used to set up the SSH key before you are logged in. The logic here is that as the SSH key pair is created, the public key is saved in your remote server; you need the corresponding private key, which the server will compare with that of the public key in order to grant you access to the remote server. If for any reason, the private key does not match the public key, you will be denied access to the server.  ( 5 min )

Best Practices for Writing Clean Code Let’s be honest: Bad code isn’t just ugly. It’s expensive. It breaks easily. It’s hard to maintain. It makes teams slower. And if you’ve ever been scared to touch a 10,000-line legacy function—you know the pain. Here’s how to avoid being that dev. Let’s break down the real-world clean code principles every programmer should follow in 2024. Name Things Like You Mean It Bad: d, tmp, a1 userEmail, tempFilePath, apiResponse Best Practices: Use meaningful, descriptive names Avoid abbreviations unless they’re standard (e.g. HTML, URL) Use camelCase or snake_case consistently Don’t reuse names for different things Pause and reflect: without comments? Write Small Functions Rule of thumb: If your function does more than one thing, break it up. Why it matt…  ( 4 min )

The other day, I was going through a list of useful UNIX commands and came across tail -f. The tail command, by default, shows the last 10 lines of a file, but you can use the -n option to see a specific number of lines. The tail -f command, however, lets you watch a file for live changes. I decided to try it out by watching a file named hello.txt in the terminal while editing it using Vim. But to my surprise, no changes appeared in the output of tail -f. This made me curious, and I started digging into what was happening. That research led me to some really interesting concepts — and made me appreciate how smart Vim’s design actually is. tail -f Really Doing? To begin with, let’s understand what tail -f does. It watches a file using its inode — a data structure in UNIX-like systems that…  ( 5 min )

The Chrome browser on my Windows 10 has not been working properly for the past few months. Whenever I tried, it wouldn't open, or it would launch and freeze instantly. I tried a couple of ways to fix it, like removing the cache, reinstalling, etc. I kept pushing off, but in the meantime, I used Brave Browser, which is good. But finally, I have solved the problem. Here's how I fixed it - and how you might be able to as well. Whenever I launched Chrome: It takes time to open, or sometimes it doesn't open It froze immediately, or It would run, but the pages wouldn't load I lived with this issue for months, then switched to Brave, but I always tried to fix it because Chrome is my go-to browser all the time. Before I found the fix, I tried: Reinstalling Chrome Removed all the extensions Cleared cached and profile data Restarting the laptop Go to your Chrome settings Now, in the settings, select the System option, and you'll see options like these or maybe other options as well. I disabled the "Use graphics acceleration when available" option, and it worked fine afterwards without any freezes occurring. After disabling it, restart Chrome. I'm not sure of the exact details, but ChatGPT explained it to me in a clear and organised manner., I wish I had tried this sooner, but you know what? I got my Chrome working normally again, and I am very happy. Did this fix work for you? Got a different solution that helped?

Introduction Traditional clinical trials are fraught with inefficiencies. The manual transcription of participant interviews, the laborious process of clinicians documenting observations, and the time-consuming effort of ensuring protocol compliance contribute to significant delays and inflated costs. These manual processes are not only resource-intensive but also prone to human error, potentially impacting data accuracy and the integrity of trial results. Voice data, in the form of spoken interviews and dictated notes, represents a vast, untapped reservoir of rich, qualitative information. However, extracting actionable insights from this unstructured data has historically been a significant hurdle.

Finally, Let Me Clear This Up Once and for All What we call programming is really just manipulating computer memory Now, a programming language is a tool humans designed But in other languages I can just say: Assembly language was created so that we don’t forget the name of a variable in memory addr... Instead of memorising the addr we can store it as short addr... Other languages I believe later tried to simplify the process... But here’s the twist Computers only understand 1 and 0 while humans understand sentences better than numbers. (E.g. if I ask you to memorise 1011011... it becomes hard. Goal is to write sentences (syntax) that we can remember. Also, programming languages themselves need to be understood by the computer. And guess what? Those compilers and interpreters are themselves programs—written in other programming languages (e.g. C++ or C)! That is... This creates a fascinating cycle Programs to write programs that write programs. Each layer builds upon the previous, hiding the complexity just so that humans can create increasingly powerful software without dealing with the tiniest detail of the hardware. So, when you ask... The answer is: Humans did. At the end of the day... It speeds up our development of a project.  ( 4 min )

I recently acquired Netatmo smart radiator valves to manage my rooms' temperature remotely. I'm not skilled at manual tasks, but I could easily replace the old thermo-static valves. I then registered the smart ones in the Netatmo app. Finally, I integrated them in my Home Assistant via the dedicated Netatmo integration. Everything was very straightforward. I noticed that each valve not only allows remote control but also offers a state with several attributes. I wanted to extract the room's temperature indicator from it. It was not as easy as I thought it was, so I want to describe how I managed to achieve it. By default, the Netatmo valve displays a multi-valued state.

InkLytic was created as an AI Content Lab to solve a specific problem: the endless loop of prompt tweaking in modern LLM-driven content creation. Prompt engineering works — until it has to scale. A single prompt might produce decent output for a blog post, but when the format changes, or the tone needs adjustment, or the audience shifts, the process starts over: rephrase, test, tweak. Here’s a typical example from early experimentation: Write a short and engaging social media post about Lionel Messi’s recent goal in the MLS. Use an excited and informal tone. Add a light-hearted emoji or two. The message should be no more than 280 characters. End with a question to encourage comments from fans. It works — once, but then comes the need for a shorter version, more formal version for Facebook,…  ( 4 min )

1. Introduction Visual quality inspection is a critical process in many industrial settings, from manufacturing assembly lines to agricultural sorting. Traditionally, these inspections have relied on manual human effort or fixed rule-based machine vision systems. However, with increasing product complexity and the demand for higher throughput, these approaches often fall short in terms of accuracy, scalability, and adaptability. This is where machine learning (ML) offers a transformative solution, enabling automated, intelligent defect detection. While cloud-based ML inference is powerful, many industrial applications necessitate "edge inference." This means deploying ML models directly onto devices located close to the data source – on the factory floor, in remote facilities, or on autono…  ( 21 min )

Microsoft 365 F1 is tailored for frontline workers who need secure, streamlined access to essential tools without the complexity of full desktop applications. While the plan supports core communication and collaboration features like Teams and Outlook (web/mobile only), it offers limited capabilities when it comes to scripting and automation. Users on the F1 plan do not have access to full desktop versions of Office apps, which restricts the use of advanced scripting tools like VBA macros in Excel or Word. Users on Microsoft 365 F1 can access Power Automate, but only at a basic level. This means they can create simple workflows using standard connectors—such as automating approval requests or notifications via Microsoft Teams. However, premium connectors and advanced process automation are not available under this plan. Organizations that require more complex automation across apps and services will need to consider a higher-tier license to unlock those features. While end-users face scripting restrictions, IT administrators managing Microsoft 365 F1 environments do have access to some administrative scripting capabilities via PowerShell. This allows them to automate user provisioning, license management, and certain security configurations. However, these tasks are limited to what’s permissible within the F1 license scope and do not extend scripting capabilities to the end-users themselves. If your business requires users to run scripts, develop custom solutions, or build automated workflows across multiple services, Microsoft 365 F1 may not be sufficient. Plans such as Microsoft 365 Business Standard, E3, or E5 offer full desktop apps, broader access to Power Automate, Microsoft Graph API, and more advanced scripting environments. Upgrading to one of these tiers ensures your team has the flexibility and tools needed for deeper customization and process automation.  ( 3 min )

Step 1: Determine Your Sensor Type Step 2: Wiring Diagram Digital Hall Effect Sensor (e.g., A3144) Vcc: Connect to 3.3V or 5V (check sensor datasheet) GND: Ground OUT: Connect to digital GPIO input Circuit: Add a pull-up resistor (~10kΩ) between OUT and Vcc (if not already onboard). OUT will go LOW when a magnet is detected, HIGH otherwise. plaintext [ A3144 Sensor ] Vcc --- 3.3V or 5V GND --- GND OUT --- GPIO (with 10kΩ pull-up to Vcc) MCU Code (Polling Example in C): c if (HAL_GPIO_ReadPin(GPIOB, GPIO_PIN_0) == GPIO_PIN_RESET) { // Magnet detected } Analog Hall Sensor (e.g., SS49E) Vcc: 3.3V or 5V GND: Ground OUT: Analog voltage (connect to ADC pin) Circuit: No pull-up needed. Output voltage is typically mid-scale (e.g., ~2.5V) when no magnetic field is present. Varies higher or lower depending on magnetic field direction and strength. plaintext [ SS49E Sensor ] Vcc --- 3.3V or 5V GND --- GND OUT --- ADC pin (e.g., PA0) MCU Code (STM32 ADC Example): c uint32_t adc_val = HAL_ADC_GetValue(&hadc1); // Convert to voltage float voltage = (adc_val * 3.3) / 4095.0; Step 3: Setup in STM32CubeMX (If using STM32) Digital Sensor: Configure GPIO as input, optionally with interrupt. Analog Sensor: Enable ADC, select correct pin, and configure sampling time. Tips Check your Hall sensor's operating voltage before connecting to a 3.3V or 5V MCU. Use decoupling capacitors (0.1µF) near the sensor for noise filtering. For multiple sensors, assign each to a separate GPIO or ADC channel. Use interrupts for real-time edge detection with digital sensors.  ( 3 min )

As the most commonly used data processing language, SQL is widely used in many scenarios, such as query and batch operating. When the amount of data is large, SQL (and stored procedure) often leads to very slow running. In this case, it needs to optimize SQL. To optimize SQL, there are some specific systemized ways. Normally, we need to check the execution plan first to find out the reason, and then recode in a targeted manner to achieve the purpose of optimization. For example, for the judgment of continuous numbers, we can use between to replace in, use the select statement to specify the field name, use union all to replace union, and rewrite exists into join. Of course, some optimization methods are available in practice, such as creating an index, and using temporary table/aggregation…  ( 13 min )

Changing your schema is part of everyday development, and ALTER TABLE ADD COLUMN is the go-to command for doing it in SQL. Whether you’re using PostgreSQL, MySQL, Oracle, or SQL Server, this command helps you evolve your tables without losing data. Here's how it works—and how to do it right. PostgreSQL/MySQL ALTER TABLE orders ADD COLUMN status VARCHAR(50); SQL Server ALTER TABLE orders ADD status VARCHAR(50); Oracle ALTER TABLE orders ADD (status VARCHAR2(50)); Define constraints from day one ALTER TABLE employees ADD COLUMN start_date DATE NOT NULL; Use meaningful names ALTER TABLE inventory ADD COLUMN last_checked DATE; Set defaults wisely ALTER TABLE tickets ADD COLUMN priority VARCHAR(10) DEFAULT 'normal'; Don’t add unnecessary columns—normalize instead. Update app logic immediately to reflect schema changes. Avoid blocking queries in production environments. Tracking reviews on a product table: ALTER TABLE products ADD COLUMN review_count INT DEFAULT 0; Keeps your schema clean while adding a useful feature. Not a fan of raw SQL? Find your table Click “Alter Table” Add your column Preview SQL Click “Execute” It’s that simple in DbVisualizer. Yes, using ALTER TABLE ... DROP COLUMN ... Use UPDATE to fill new columns with calculated values. Some do. PostgreSQL, yes. MySQL, not always. ALTER TABLE ADD COLUMN is more than just a syntax trick—it’s a key part of adapting to change. Use it wisely, document your updates, and lean on tools like DbVisualizer when needed.

In the intricate world of distributed computing, where applications are often spread across multiple machines, sometimes continents apart, the ability for these disparate components to communicate seamlessly is paramount. This is where the concept of a Remote Procedure Call, or RPC, comes into play. At its core, RPC is a powerful mechanism that allows a program on one computer to execute a procedure (a subroutine or function) in another program located on a different computer, or even in a different address space on the same computer, as if it were a local call. This abstraction simplifies the development of distributed applications by hiding the underlying complexities of network communication. Imagine you're a chef in a busy kitchen (your local program).

As a developer in the past, I’ve always been drawn to systems — clean logic, predictable outcomes, elegant solutions. But trading? Trading is the exact opposite. It’s messy, unpredictable, and deeply human. At first, I tried to approach the market like I do software — build a strategy, test it, automate where possible. But the markets don’t run on code alone. They run on psychology, emotion, global events, and a thousand invisible threads. That clash between logic and chaos forced me to rethink everything I thought I knew about building systems. Trading isn’t just about algorithms or signals. It’s about mindset, discipline, and adapting your approach when the unexpected hits. Over time, I learned to treat my trading strategy like I do a project: start with a clear structure, iterate fast, test assumptions, and most importantly — expect the system to fail sometimes. It’s a humbling process. But it’s also one that makes you better, not just as a trader, but as a developer and thinker.  ( 3 min )

A destructor (del) is used to clean up resources when an object is about to be destroyed. It doesn't run immediately after an object is no longer used, but is triggered automatically by Python's garbage collector when there are no more references to that object. Important Points: Python automatically calls the destructor (del) When no more variables reference an object, Python automatically calls del() (if defined). When is del() useful? You might define a destructor when: You need to close a file. You don’t manage memory directly (like in C/C++). Python handles memory. You can’t force the garbage collector to run at an exact time (though you can suggest it using gc.collect()). 🧠 Analogy It watches which objects you're using. When you stop using something and forget it, the housekeeper eventually throws it out. If you say del obj, you're telling the housekeeper: "Hey, I don't need this anymore." But the housekeeper decides when to actually throw it out.  ( 3 min )

🧠 1. Overview of Stale Closure in React In React, a common but subtle bug is the "stale closure" — which happens when a function inside a component uses an outdated value, not reflecting the current state or props. This often leads to unexpected behavior, especially in callbacks, useEffect, or asynchronous logic. Understanding how JavaScript creates closures and how React handles re-renders is key to avoiding this issue. Scope defines the visibility of variables. In JavaScript, we have function scope and block scope. A closure occurs when a function remembers variables from the scope where it was defined, even if it's executed elsewhere. Example: function outer() { let count = 0; return function inner() { console.log(count); // closure retains the value of count }; } Closure…  ( 4 min )

In this article, we review a variable named noOp. This is something I found in logger.ts file in the n8n source code. When I saw this line below, what it tells me straight away is that it’s something to do with no operation : const noOp = () => {}; When you look at this, it’s doing nothing. I mean, it’s just an arrow function that returns an empty object So you might be wondering how is this used? So that’s what we will find out. When I click on the no-op, these are the symbols I found on the right side and in the same file, I see that this variable is used at line 103. When I click and jump to that line, you will see that this is inside a function called setLevel. private setLevel() { const { levels } = this.internalLogger; for (const logLevel of LOG_LEVELS) { if (levels[logLe…  ( 5 min )

Recently, a zk user reported that they couldn't tab through all interactive elements on a zul page. This behavior is tied to a little-known setting deep in Safari’s Settings. Keyboard navigation is essential for accessibility, allowing users who rely on keyboards or assistive technologies to navigate without a mouse. It also benefits power users who prefer using Tab for faster navigation. If this doesn't work as expected, especially on Safari — one of the major browsers — it can be a frustrating and invisible blocker. Assuming I create a page with a textbox, menubar, menuitem, anchor link, intbox, navbar, and navitem, and visit it with various browsers. When pressing the Tab key in Chrome (136.0), Firefox (138.0), and Edge (136.0), I can successfully move through all components, including each link, menu item, and nav item. But within Safari (18.4), I can only focus on some components. Safari will skip most menu items, links, and nav items. You can try the page on zk fiddle with your Safari. I found the root cause is: The option “Press Tab to highlight each item on a webpage” in Safari Settings is unchecked by default. After I checked that option, I can focus on all components by pressing the Tab key. If it’s unchecked, you have to press Option + Tab key to focus on all components.  ( 3 min )

API versioning is an indispensable discipline in the lifecycle of any application programming interface. As APIs evolve with new features, bug fixes, or fundamental architectural changes, a robust versioning strategy is paramount to ensure smooth transitions for client applications and maintain a stable ecosystem. Many development teams, drawing from their experience with software libraries, naturally gravitate towards semantic versioning (SemVer), a widely adopted standard that uses a three-part MAJOR.MINOR.PATCH numbering scheme. However, while SemVer offers undeniable clarity for software packages, its direct and granular application to version REST API endpoints can introduce unnecessary complexity, operational overhead, and a less-than-ideal experience for API consumers.

Most developers who works with AI eventually hit the same wall - context. You can pipe tools together, chain AI prompts, or write clever workflows, but at some point, you realize your agent isn’t really thinking. It’s reacting. You need something different. I hope you used n8n, LangChain, or a similar tool, and you probably created pipelines where each AI step feeds the next. That works for formatting data or guiding workflows. And it is fine for simple agents, but what if your agent needs to remember? What if it needs to learn across conversations? How about adapt to changes? ... or retrieve knowledge like a human? Before diving into the code, let’s break down AI memory into three simple categories: Stateless (No Memory): Short-Term Memory: Long-Term Memory: try to remember remembers prev…  ( 5 min )

As someone who constantly learns and writes about AWS, I’ve found myself often asking: “What should I build next?” Not just for the sake of learning—but to challenge myself, grow professionally, and create blog posts that actually help others. But here’s the thing… coming up with project ideas is hard. With over 200 AWS services, it’s easy to feel overwhelmed. I’d often sit down thinking: Should I build something with Lambda? Maybe try a serverless ETL pipeline? What’s a good way to combine AI and AWS? But instead of starting, I’d spiral into: Paralysis by analysis. It turns out I wasn’t alone. Many AWS learners and professionals face the same challenge. That’s when an idea struck: What if I could describe: My experience level The AWS services I want to learn or showcase ...and an AI c…  ( 5 min )

the "devlog" (ugh) series will be just a kind of public exhibitionist diary to self-indulgently share some work I did. nothing big. nothing serious. OK, chatGPT... uh... tell me what to say now. Should I be funny, serious? where are the hiring departments? After reaching a creative-stopping-point or end-token in the BeaconAI project from my last post, I decided the logical next move was to start attempting to locally deploy an LLM and dig a bit deeper into the finer details. The model I decided to work with was Mistral. I deployed a quantized version, as my CPU/GPU pair is unable to effectively deploy the full version. I was able to get it up and running, and I used it for generating outputs in the BeaconAI application. The logical next step was to attempt PEFT fine tuning. Parameter Effic…  ( 5 min )

Personalization is at the heart of modern digital experiences. Whether it’s suggesting the right product, showing tailored promotions, or dynamically updating content, users expect fast, relevant interactions across every touchpoint. But here’s the challenge: the closer the personalization logic lives to the backend, the more latency and potential bottlenecks you introduce. That's where Akamai EdgeWorkers change the game. Edge computing has revolutionized how we think about performance. Instead of relying entirely on origin servers, we can now push business logic and personalization closer to the user—right to the edge. Traditionally, personalized content is generated at runtime by backend services. This often involves API calls, session validation, user segmentation, and rendering logic.…  ( 5 min )

Managing the lifecycle of your Amazon RDS databases just got easier! Amazon RDS now provides a simple way to view engine support dates for your database engines — directly from the RDS API or AWS CLI. With this new feature, you can now: ✅ View start and end dates for RDS Standard Support ✅ Check if RDS Extended Support is available ✅ Get both support periods in a single response (if available) This applies to Amazon RDS and Amazon Aurora major engine versions. Previously, finding out when your database engine version would reach its end of support meant digging through documentation or announcements. Now, you can fetch this information programmatically, making it easier to: 🗓️ Plan upgrades ahead of time 🛡️ Ensure compliance and security 🚫 Avoid running unsupported versions Here’s how you can check support dates for PostgreSQL 11: aws rds describe-db-engine-versions \ --engine postgres \ --engine-version 11 \ --include-all Output (simplified): { "Engine": "postgres", "EngineVersion": "11", "SupportDescription": { "StandardSupport": { "StartDate": "2018-10-01", "EndDate": "2024-11-09" }, "ExtendedSupport": { "EndDate": "2026-11-09" } } } Now you know exactly when your engine support ends — and whether Extended Support is an option. This feature is a great step toward proactive database lifecycle management. If you're running critical workloads on Amazon RDS or Aurora, this new visibility helps ensure business continuity, security, and compliance. ➡️ Start using it today with the AWS CLI or API! Let me know what you think about this new feature. Are you planning to use it to manage your DB upgrades better?  ( 4 min )

If you're building scalable applications in Node.js, there's a good chance you've considered Dockerizing your app to make it more portable and consistent across environments.

Understanding Re-renders with React Context and how to avoid waste Have you ever wondered why your component in React re-renders even without anything visibly changing? Let's understand this with simple examples – as if we were assembling a block game. Imagine three components, one inside the other: And let's say you have a Context at the top (App) that shares some data with everyone below. If re-renders (for any reason), all components below it also re-render: App -> Container -> SearchContainer -> Search Even if only the last one (Search) actually uses the Context! If Container and SearchContainer don't need to change, we can avoid the effort of re-rendering them by using…  ( 5 min )

Writing clean code in React is not just about making it work—it's about making it readable, maintainable, and scalable. Whether you’re building a simple to-do app or a large-scale application, following clean code principles will make your life (and your team’s) much easier. Here are some practical tips to help you write clean React code 👇 📁 Organize Your Folder Structure Structure your project in a scalable way. Avoid dumping all files in one folder. Bad: /src Good : 🧩 Use Functional Components & Hooks Prefer functional components with hooks over class components. // ✅ Clean function Welcome({ name }) { return Hello, {name}! ; } 📦 Break Components into Smaller Pieces Keep components small and focused on one task. If a component is doing too much, break it into smaller ones. // ❌ Bad const Dashboard = () => { // fetching, rendering UI, handling logic... all in one }; // ✅ Good // Dashboard.jsx → uses , , etc. 🧹 Clean Up useEffect Always clean up side effects to avoid memory leaks. useEffect(() => { const interval = setInterval(() => { console.log("Running..."); }, 1000); return () => clearInterval(interval); // ✅ cleanup }, []); 🧪 Write Reusable Hooks Extract reusable logic into custom hooks. // useToggle.js import { useState } from 'react'; export function useToggle(initialValue = false) { const [state, setState] = useState(initialValue); const toggle = () => setState(prev => !prev); return [state, toggle]; } 🚀 Final Thoughts Easy to read 👓 Easy to reuse ♻️ Easy to test 🧪 Easy to maintain 🛠️ You don’t need to be perfect—just aim for improvement step by step.

The Illusion of Progress: Analyzing Tesla’s Optimus Robot Demonstrations A Carefully Curated Display Observing Tesla’s Optimus bot demonstrations, one might find a pattern emerging: the videos are invariably short, edited together to suggest a seamless execution of movement. This is, however, by design. The underlying Large Language Model (LLM)-based approach used in Optimus starkly contrasts with traditional heuristic-driven robotics. Unlike heuristic models, which rely on pre-defined logic and task-specific programming, Optimus leverages machine learning techniques to generate actions. What this means is that instead of executing fully autonomous behaviour, the bot performs discrete snippets of movement—ones it has learned from sequences such as dance routines and combat kat…  ( 3 min )

Welcome to the fascinating world of deep learning! If you've ever wondered how computers can recognize objects in images, distinguish between different types of clouds, or even power automated passport control systems, you're about to uncover one of the key technologies behind it: Convolutional Neural Networks (CNNs). These powerful neural networks are specifically designed to handle image data and have revolutionized computer vision over the past decade. Before diving into CNNs, let's understand how computers perceive images. Digital images are made up of tiny squares called pixels. In a grayscale image, each pixel holds a numerical value representing a shade of gray, typically from 0 (black) to 255 (white). For color images, each pixel usually has three numerical values representing th…  ( 9 min )

If you are a JavaScript developer, you might have ran into error messages like: Failed to extract text from the file Failed to save entity And so on... But what exactly led to failing of an entire high-level operation? We don't know the answer because we didn't do a good enough job to preserve the error context, when throwing a specific error that is a symptom of a more low level cause. For years, JavaScript developers have struggled to preserve appropriate error context when throwing exceptions, as there was no in-built mechanism provided by the language to attach error cause, unlike other languages like Java, Python and C#. This problem was solved by Node, when they finally added a cause property to their Error constructor in v16.9.0, which means you could now throw exceptions like so: t…  ( 5 min )

Writing sample data: started with small amount from Study Buddy - need to follow "Contact Book - Our Very First Database" from AppDev1 section "custom rake tasks" Association Accessors: Direct Associations: belongs_to default is opposite: belongs_to adds an automatic validation to foreign key columns enforcing the presence of a valid value unless you explicitly add the option optional: true. So: if you decided to remove the null: false database constraint from any of your foreign key columns in the migration file (e.g., change t.references :recipient, null: false ... to t.references :recipient, null: true ...), then you should also add the optional: true option to the corresponding belongs_to association accessor. So remember — if you’re ever in the situation of: you’re trying to save a record the save is failing you’re doing the standard debugging technique of printing out zebra.errors.full_messages you’re seeing an inexplicable validation error message saying that a foreign key column is blank now you know where the validation is coming from: belongs_to adds it automatically so figure out why you’re not providing a valid foreign key (usually it is because the parent object failed to save for its own validation reasons) Direct associations: has_many belongs_to, there should be an inverse has_many.

onChange={handleChange} vs onChange={(e) => handleChange(e)} In modern React development, handling events is a foundational skill for building responsive, data-driven interfaces. Whether you’re crafting a dynamic form or building reusable components, knowing how to manage events efficiently can make your code simpler, more readable, and more performant. Today, we’ll break down a deceptively simple difference that many React devs gloss over: onChange={handleChange} vs onChange={(e) => handleChange(e)} At first glance, both seem to do the same thing—pass the event to a handler. But there are subtle differences that matter in real-world apps. Let's explore them together.

An American tourist in the United Kingdom was reportedly drugged by an individual posing as a taxi driver, who stole the tourist's $123,000 in Bitcoin stored on a cell phone. According to a report from My London, Jacob Irwin-Cline went out to a London bar and had several drinks before calling an Uber to take him home. Cline said that he did not thoroughly check the details of the Uber ride on his phone and left with a random private cab driver resembling the Uber driver at first glance, but driving a different vehicle — a detail Cline would only discover after the incident. Once inside the vehicle, the US tourist said the driver offered him a cigarette, which Cline said was likely laced with a rare and potent sedative drug called scopolamine. Cline added that the cigarette made him feel …

Though a majority of members of the US Senate voted to advance a bill to regulate payment stablecoins on May 20, high-ranking Democrats are planning to propose an amendment to the legislation to address President Donald Trump’s connections to the cryptocurrency industry.

OpenAI is planning to develop AI “companion” devices that will integrate artificial intelligence capabilities with everyday life, potentially opening the door to a new high-tech innovation used alongside laptops and smartphones. In an interview with The Wall Street Journal, OpenAI CEO Sam Altman said he and designer Jony Ive are developing these secret devices for mass consumption, with plans to ship 100 million units upon launch. Ives joined OpenAI after his startup, io, was acquired by Altman’s company in a $6.5 billion deal, the Journal reported on May 21.  Neither Altman nor Ives specified what these companion devices would look like or how they would operate. Ives simply referred to them as a “new design movement” that would be similar to Apple’s family of hardware and software integr…

Key takeaways: Solana’s bull flag pattern projects a rally to $260, but low spot buy volumes have analysts advising caution. After briefly dropping to $160 from $184, Solana (SOL) is attempting to reclaim a position above its key resistance at $180 for a second consecutive week. With Bitcoin (BTC) hitting an all-time high, market speculators are banking on eventual capital rotation, which could pump major altcoins like SOL toward new highs. Solana shows promising signs on the daily chart, forming a textbook bull flag pattern after a strong uptrend. While SOL prices currently trade under $180, a breakout above this level could propel SOL toward its first target at $200, with further upside potential to $220 if momentum sustains.

Crypto exchange Kraken is planning to offer non-US customers the option of trading tokenized US stocks, part of the company’s push to offer more traditional assets via tokenization. The products will be offered through Backed, a new Kraken partner, according to a statement shared with Cointelegraph. Tokens representing the stocks will be stored on the Solana blockchain due to its “unmatched performance, low latency and thriving global ecosystem,” the statement said. “The whole point of crypto is that we're able to see things very transparently,” Kraken co-CEO Arjun Sethi said during Solana's Accelerate event on May 22. ”It's decentralized. It is open-source. You can innovate as quickly as possible, and there's no reason why companies like us can't morph to do that." The decision to incorpo…

California Representative Maxine Waters, ranking member of the US House Financial Services Committee, has announced plans to introduce legislation “to block [Donald] Trump’s memecoin and stop his crypto corruption.” In a May 22 notice, Rep. Waters said the Stop Trading, Retention, and Unfair Market Payoffs (TRUMP) in Crypto Act of 2025 bill would be aimed at blocking the US President, Vice President, members of Congress, and their families from engaging in “crypto crime.” The US lawmaker referred to Trump and his wife, Melania, issuing personal memecoins in January, his family launching a stablecoin, USD1, through the crypto platform World Liberty Financial, and the president attempting to establish a national Bitcoin (BTC) reserve as his sons back a BTC mining venture. “Donald Trump is preparing to dine with the top donors of his memecoin who’ve made him, and his family, richer,” said Waters, adding: “Trump’s crypto con is not just a scam to target investors. It’s also a dangerous backdoor for selling influence over American policies to the highest foreign bidder.” HR 3573, Stop TRUMP in Crypto Act of 2025, introduced by Rep. Maxine Waters. Source: House Financial Services Committee Democrats Waters’ bill was one of many actions announced to oppose the president’s dinner to reward memecoin holders.

This is a developing story, and further information will be added as it becomes available.

Key points: Mixed results for US jobless claims fail to dent risk-asset enthusiasm. Despite concerns over the bond market, Bitcoin and stocks enjoy stability at the start of the Wall Street trading session.

Key takeaways: Bitcoin’s rally to new price highs happened as funding rates and trading sentiment remained unusually subdued. Rising stablecoin supply and global M2 growth indicate untapped liquidity and the potential for further price increases. Long-term holders are not aggressively selling, reflecting their expectation for continued Bitcoin price appreciation. Bitcoin (BTC) hit a new all-time high on May 21, with prices rising to $111,860 on Binance on May 22, but the markets lack the state of frenzy associated with new highs. Economist and crypto commentator Alex Krüger noted that “this is the least euphoric new all-time highs” for Bitcoin, after highlighting subdued funding rates for Bitcoin across crypto exchanges.

DeLorean launched an onchain reservation system and non-fungible token (NFT) marketplace for its upcoming electric vehicle launch, introducing a new blockchain-based approach for reserving and reselling cars. According to DeLorean, its Build Slot NFT collection grants holders priority access to purchase DeLorean’s upcoming electric car, Alpha 5 EV. The model is the carmaker’s first vehicle in over 40 years, inspired by the iconic flux capacitor from the movie Back to the Future. The company created an exclusive marketplace for its NFT holders, in which users can buy or trade the NFTs using the USDC (USDC) stablecoin on the Sui network and will be able to earn rewards. DeLorean says that each vehicle’s history and performance data will be recorded onchain through the FLUX protocol, includin…

Opinion by: Ahmad Shadid of O.xyz Semiconductors scored a rare exemption from US President Donald Trump’s aggressive reciprocal tariffs, but the relief is symbolic at best. Most semiconductors enter the US embedded in servers, GPUs, laptops, and smartphones.  The finished goods remain heavily tariffed, some with duties reaching up to 49%. The exemption looks good politically but delivers little practical benefit. Nvidia’s DGX systems, crucial for training advanced AI models, do not fall under the exempted HTS codes. Nvidia could pay effective tariffs nearing 40% on these vital components. Such costs threaten to stall critical AI infrastructure projects across the country.  Semiconductor tariffs may compromise the goal of the CHIPS Act. The act promised tens of billions of dollars in subsid…

As the question of stablecoin regulation heats up in the US Senate, so has the issue of which members are personally invested in cryptocurrencies and cryptocurrency firms. On May 19, the Senate voted to invoke cloture and move ahead with the GENIUS Act, which would provide a regulatory framework for stablecoins. The measure passed 66-32, with 16 Democrats supporting the bill. Democratic concerns over corruption and politicians’ ties to cryptocurrency firms made the bipartisan move controversial. After the vote was finished, Colorado Senator Michael Bennet introduced the STABLE GENIUS Act. The bill would prevent members of Congress from issuing or investing in digital currency and require them to put their crypto in a blind trust while in office. Bills to prevent members of Congress from i…

Cryptocurrencies and non-fungible tokens (NFTs) can help investors protect their eroding purchasing power during an era of exponential currency debasement, according to analysts and industry leaders. Investing in digital assets is becoming increasingly important in the “world of the exponential age and currency debasement,” according to Raoul Pal, founder and CEO of Global Macro Investor. “You don’t own enough crypto. When you do, you don’t own enough NFT’s, as art is upstream of wealth. Both will never be this cheap again,” Pal said. NFTs are “the single best long term store of wealth I know and you get to buy it before network effects kick in,” he added in another response.

What if a financial system could run itself not by burning electricity, but by rewarding good behavior? That’s the promise of staking, a mechanism that powers many modern blockchains by turning users into network operators.  In this week’s episode of The Clear Crypto Podcast, hosts Gareth Jenkinson and Nathan Jeffay sit down with StarkWare’s Noam Nisan to unpack how this trustless engine works, why it matters and what’s really at stake. Understanding staking Jeffay began by highlighting how staking is part of the backbone that keeps the blockchain running, and runs itself, with volunteers. “By doing this, they’re saying, OK, we’re taking this task of running the blockchain seriously. Here's some of our money. We're putting it down. We're showing that we're serious about doing this.” To he…

Key takeaways: Memecoins like Fartcoin, WIF, SPX6900, and Popcat are outperforming Bitcoin in the short term amid renewed crypto market euphoria. Bullish technical patterns signal more upside for top-performing memecoins. Popcat stands out with a potential 350% rally, while Fartcoin and WIF also eye significant gains in the coming weeks. Bitcoin (BTC) has surged 7.35% over the past three days, hitting a new all-time high near $112,000 on May 22, but memecoins are stealing the spotlight.

The United Kingdom’s Court of Appeal partially dismissed a lawsuit brought by Bitcoin SV investors against major crypto exchanges, including Binance, for allegedly conspiring to delist the token in 2019. In a judgment handed down on May 21, the court ruled that investors who held BSV through the delisting period (classified as “sub-class B”) were not entitled to billions in speculative damages based on BSV’s hypothetical growth. These investors had claimed over 8.9 billion British pounds ($11.9 billion) in damages, asserting that Binance’s delisting deprived holders of the chance to profit from BSV’s potential rise to a “top-tier cryptocurrency” like Bitcoin (BTC) or Bitcoin Cash (BCH). The court rejected this “foregone growth effect” theory, stating, “BSV was obviously not a unique crypto…

Cetus, a decentralized exchange (DEX) built on the Sui blockchain, has reportedly suffered a massive exploit that may have drained more than $200 million worth of digital assets. Pseudonymous Web3 researcher COMDARE3 posted on X that “users report” that Sui-based DEX Cetus is being exploited.” He also shared a screenshot of Cetus market data on DEX Screener, showing many assets losing well over half of their value over the last 24 hours.

A crypto trader spent $3.8 million to buy Ether at a significantly higher price after selling the asset for almost the same amount about a month ago.  On May 22, blockchain analytics firm Lookonchain reported that a crypto wallet spent $3.8 million to purchase 1,425 Ether (ETH) at $2,670 per coin, reentering ETH after a major rally.  On April 13, the same wallet sold 2,522 ETH for $3.9 million, when the asset was trading at about $1,570, a decision that, in retrospect, looks poorly timed.  “Think twice before selling your bags,” Lookonchain wrote, highlighting the potential gains if the trader just held on to their Ether instead of selling and repurchasing it at a higher price point.  Whale buys ETH after selling over a month ago.

Crypto awareness in Singapore has reached an all-time high, with 94% of respondents in a recent survey indicating familiarity with at least one digital asset. However, ownership declined, falling to 29% in 2025 from 40% the previous year, according to Independent Reserve’s fifth annual Singapore Crypto Market Survey released on May 21. The survey, conducted in February with 1,500 participants, revealed that men remain more active in crypto investing than women, 35% compared to 24%.

The market cap of the world’s first cryptocurrency, Bitcoin, surpassed that of retail and tech behemoth Amazon on “Bitcoin Pizza Day.” Market data shows that Bitcoin (BTC) had a market cap of $2.205 trillion at the time of writing, $70 billion more than the $2.135 trillion Amazon valuation. “By surpassing Amazon in terms of capitalization, Bitcoin has attracted even more attention from the non-crypto audience,” said Alex Obchakevich, founder of Obchakevich Research. Obchakevich said the latest rally “will strengthen confidence in Bitcoin and lead to new injections into the crypto market.” The surge came as Bitcoin set a new all-time high and traded above $110,000, which Obchavich said will “attract new investors to large funds.” Obchakevich noted that institutional players continue to ex…

Key takeaways ChatGPT-powered AI agents automate trading tasks using natural language prompts and API integrations, improving speed and consistency. Successes occur when ChatGPT is used as a support tool, not a fully autonomous trading system. Failures happen when traders over-rely on ChatGPT without real-time data, proper risk management or manual oversight. Regulatory focus on AI in trading is increasing, with new frameworks emerging to ensure transparency, accountability and compliance. What if a crypto trader didn’t need to constantly check charts, worry about emotions, or stay up all night watching for sudden price swings? What if those tasks could be handled by an intelligent agent that understands instructions in plain English — and reacts within milliseconds? That’s where Chat…

Travelers using cryptocurrency for booking arrangements spend more than twice as much as regular travelers using fiat money, according to a joint report from Binance Pay and crypto travel platform Travala shared with Cointelegraph.

Crypto travelers are also outspending their fiat counterparts, with an average booking value of  $1,211 per transaction, over 2.5 times more than fiat users who spend $469. Additionally, the report said crypto users were three times more valuable over their lifetime due to longer stays and higher repeat bookings, with crypto travelers 57% more likely to make a repeat hotel purchase.

David Sacks, US President Donald Trump’s top adviser on crypto and artificial intelligence, said the administration expects the stablecoin bill to clear the Senate with bipartisan backing. “We have every expectation now that it’s going to pass,” Sacks told CNBC on May 21, following a key procedural vote that saw 15 Democrats join Republicans to clear the filibuster threshold. The Guiding and Establishing National Innovation for US Stablecoins (GENIUS) Act is the most advanced federal effort yet to establish a legal framework for dollar-pegged digital assets. Sacks said the bill could trigger “trillions of dollars” in demand for US Treasurys by unlocking stablecoin growth under clear rules. “We already have over $200 billion in stablecoins — it’s just unregulated,” he added. “If we provide …

Key points: Bitcoin all-time highs matter little to those seeing a BTC price correction as long overdue. Both the latest surge and the bull market itself are on borrowed time, traders say.

What is shilling in crypto? At its core, shilling is the act of artificially promoting a cryptocurrency or token, often with exaggerated claims, to increase its price or popularity.  But what’s the goal?  Hype it up, get others to buy in, and then cash out, leaving latecomers holding the bag. Shilling can come from anyone: influencers, anonymous accounts or even high-profile figures with political or financial clout. The common thread is manipulation: It’s not about educating you or building real value but pumping hype for personal gain. Unfortunately, the line between enthusiastic promotion and outright deception can be thin, and many fall victim without realizing it. That’s why it’s critical to learn how to spot the signs early. …

Decentralized finance platform Synthetix has axed its $27 million plan to acquire crypto options platform Derive after negative community feedback.

For years, IT professionals have balanced a critical dichotomy: essential yet monotonous daily tasks consuming their valuable expertise. Microsoft's bold integration of artificial intelligence within Microsoft 365 challenges—and changes—this paradigm entirely. As AI quietly assumes the ordinary, IT admins can step forward into the extraordinary, shifting from managing minutiae to shaping strategy. What happens to an IT admin freed from repetitive chores? They're empowered to innovate, wield influence, and transform their role from problem-solvers into organisational visionaries. Imagine—just for a moment—a day without countless clicks, portal navigation, or routine queries. Imagine speaking naturally to your administrative tools, eliciting immediate insights and seamless summaries. Enter M…  ( 6 min )

Today I found out that disabling a form field in Rails means it won't be submitted at all. I used disabled: true thinking I could show a value that users can’t change — and I could — but the downside is that the value doesn’t get sent to the controller. I learned that if I want the value to be shown but not editable and still be passed in the form data, the correct attribute to use is readonly: true. This small difference between disabled and readonly matters when you're depending on that data in your controller. It’s not a Rails issue; it’s how forms work in general. This was a helpful thing to learn today. Hopefully it saves someone else a bit of time too.  ( 3 min )

In very simple terms, Machine Learning is the process of using existing data to create a mathematical function. For example, we have an ice cream shop's data that includes the average temperature of the past 30 days, along with the number of ice creams sold on each day. We can analyze this data (average temperature and number of ice creams sold) and can create a mathematical function that fits with the existing data. Further, this function can take the average temperature as input and return the prediction of the number of ice creams that can be sold on that day. From the existing data, the data that we use as the condition, in our case, the average temperature, is called a Feature. The main data that we are targeting to predict, in our case, the number of ice creams sold, is called the Label (also known as the target variable in technical terms). In mathematical terms, the features are referred using xxx . Hence, the features can be represented as [ x1,x2,x3,...,xnx_1, x_2, x_3, ..., x_nx1​,x2​,x3​,...,xn​ ]; whereas the label is referred to as yyy . The process of defining the function using the existing data is called Training. This is the step where the model (a general term used for the mathematical function we create) learns the relationship between features and labels. Further, the process of using the defined function to get the predicted value is called Inferencing. In mathematical terms, the function is referred to as f(x)f(x)f(x) . Moreover, the predicted value by the function is referred to as y^=f(x)\hat{y} = f(x)y^​=f(x) Final Words This was the fundamental knowledge of Machine Learning.  ( 3 min )

Ever feel like the tech world speaks a secret language designed purely to confuse you? Like they're throwing around terms like "API" just to watch your eyes glaze over? It's okay, you're not alone. Sometimes, tech jargon feels less like helpful terminology and more like a robotic chant only understood by machines fueled by blinking lights and questionable energy drinks. But here's a little secret: that scary-sounding "API" is actually something you interact with constantly in your everyday life, probably even before you've had your morning caffeine fix. And it's not actually that complicated when you break it down. So, let's ditch the confusing code for a minute and talk about something much more important: coffee. Because, believe it or not, understanding how you get your glorious cup of …  ( 9 min )

The Mobility Database is an international catalog of public transit data for transit agencies, rider-facing apps, technology vendors, researchers, and others to use. It features over 3,000 General Transit Feed Specification (GTFS) and GTFS Realtime feeds. Here's what we did in May: Search by GTFS feature 🤔 Curious to know which GTFS features different agencies support? This new search filter allows you to easily discover feeds based on the features they’ve implemented, such as Fares, Flex or Pathways. Explore here. Update: TransitFeeds will be deprecated by December 2025 The Mobility Database is replacing TransitFeeds.com as the central open platform for discovering transit data.

When I first started using Jenkins, I began with Freestyle jobs, which felt straightforward—just click, configure, and run. Then I explored Pipelines and learned how they differ by building a Java app, scripting from the terminal, and using Git to manage project files. 1. Building with Freestyle Jobs Build my Java app using Maven Run shell scripts (after configuring Jenkins to recognize Git Bash) Understand that the pom.xml file is essential for Maven builds because it defines the project structure and dependencies Freestyle jobs provide an easy way to experiment, but there are limitations when the build process becomes more complex. 2. Exploring Pipelines – Defining Builds as Code Pipeline jobs allow defining every build step as code within a Jenkinsfile. Instead of using the UI, the process is scripted, for example: pipeline { agent any stages { stage('Build') { steps { echo 'Running build...' } } } } This approach enables version control of build processes, clearer visibility into each stage, and better scalability for complex workflows.  ( 3 min )

An organization’s structure determines how people communicate, make decisions, and stay motivated. Groups employees by specialized functions (e.g., Marketing, Finance). Pros: Deep expertise within departments Clear career paths and supervision Cons: Silos may form, limiting collaboration Slow decision-making across functions Organizes units around products, markets, or regions. Pros: Strong focus on specific product lines or geographies Faster response to local needs Cons: Resource duplication across divisions Potential competition for corporate support Combines functional and divisional chains of command. Pros: Flexible deployment of talent Encourages cross-functional teamwork Cons: Dual reporting can confuse roles Political jockeying for scarce resources Centers on a small core organization that outsources major functions. Pros: Highly adaptable to change Leverages external experts Cons: Less direct control over partners Dependency on external stability 5. Team-Based Structure Organizes around self-managed, cross-functional teams. Pros: High employee engagement and ownership Rapid innovation through diverse perspectives Cons: Role ambiguity can arise Requires strong team-building and conflict-management skills How Structure Shapes Behavior • Communication: Hierarchies vs. networks change how information flows. • Decision-Making: Centralized vs. decentralized structures affect speed and empowerment. • Motivation: Clear roles boost certainty, while fluid teams drive creativity.  ( 3 min )

In android applications, the programs and screens which users can interact are presented by activity. Every application have at least one activity, but not limited to one. There are several lifecycle process of activity: All of these lifecycle of activities are having their own callback methods, to run certain functions when they are reaching certain state: Activity First Created Initialization and basic setup of the activity you also need to call what layout to be served to UI Activity becoming visible to user User are able to see the activity, but not yet responsive for user interaction Preparation before becoming interactive Activity starts interacting with user For example, when you gets called when using your phone and you answer the call, after the call it will give you the resume Captures user input, usually where the implementations of app core's functionality is done This First 3 callback function will be created and called when open app System changed focus from the current activity For example, when you use application and open another app, onPause() will be called.

Step 1: Understand Superconductivity What’s Superconductivity? At super low temperatures, certain materials like niobium or aluminum lose all electrical resistance, becoming superconductors. Electrons pair up into Cooper pairs, moving through the material without losing energy. Why This Matters: Superconductivity allows quantum effects, like tunneling, to take place without interference from electrical resistance. This sets the stage for a Josephson junction. Think of It Like: A frictionless highway where cars (electrons in this case) can zoom along without slowing down. Step 2: Build the Josephson Junction Structure: A Josephson junction is made by sandwiching a super thin insulating layer (like aluminum oxide, just a few nanometers thick) between two superconducting materials (e.g., niob…  ( 4 min )

TDZ Pro’s Hidden Growth Weapon: Why a Customized CRM and Data Mining Team Beats Automation Every Time Marcus ・ May 15 #crm #sales #datamining #startup  ( 2 min )

It started from the idea that it would be cool to have an automatically generated "zen koan" play out at a specified interval, automatically generated using prompt-engineering to created varied outputs. For example, every hour between 8AM and 8PM, I would call the API with a prompt like "Inspire me with amazing life energy and tie in _____" and the blank would be filled in with a random word or phrase so that each generation was fresh. Then this would be turned into audio with TTS and played through the speakers. This was just the basic idea, and I quickly began building this using Python scripting and ample help from GPT to accelerate the process. Quickly I realized it would be more fun to make it a creative app, and ideas began to flow. Eventually it became more to my taste as an artisti…  ( 10 min )

As a front-end dev still sharpening my skills, JavaScript keeps surprising me. Here are 5 simple but powerful JS tricks I wish I had discovered earlier — and now use all the time: 1. Optional Chaining (?.) const userName = user?.profile?.name ?? "Guest"; 2. Destructuring for Cleaner Code const { name, age } = person; const [first, second] = colors; 3. Array.some() and Array.every() items.some(item => item.stock > 0); items.every(item => item.stock > 0); 4. Spread & Rest Operators const newArray = [...arr1, ...arr2]; function sum(...nums) { return nums.reduce((a, b) => a + b, 0); } 5. Short-Circuit Evaluation && and || to simplify conditional logic: isLoggedIn && showDashboard(); const user = input || "Anonymous"; These tricks aren't advanced — just practical. Once I started using them, my code became much cleaner and easier to understand. If you're learning JavaScript, give these a try! What are your favorite JS tips? Drop them below!  ( 3 min )

Introduction YAML (YAML Ain’t Markup Language) is a human-readable data serialization language designed for configuration and data interchange. Unlike XML or JSON, YAML uses minimal syntax and indentation (spaces) to represent structure, making it easy for humans to read and write. Developers encounter YAML all the time: it’s the backbone of many DevOps tools (Kubernetes manifests, Docker Compose files, Ansible playbooks, CI/CD pipelines, GitHub Actions workflows, etc.). For instance, GitHub Actions workflows are defined in YAML files (in .github/workflows/), since “YAML is a markup language that’s commonly used for configuration files”. Because of its ubiquity in modern tooling and its focus on readability, understanding YAML is invaluable for developers. YAML’s syntax is defined by a …  ( 9 min )

I’m developing a parental control app (Android 14-15, Android Studio Java) and need to take screenshots on a child’s Android smart phone(Samsung A15). However, all the common solutions I’ve found is just the MediaProjection API—have major limitations. For instance, it requires user approval every time the device reboots, and apps like YouTube can interrupt the recording process when they enter full-screen mode. Despite this, I’ve seen some parental control apps like Ever Accountable that request permission only once(Not Screen Recording-Installed Apps, but Accessibility, Device Administrator, Usage Stats and Notifications), can take screenshots silently in the background, and are not affected by interruptions from other apps. Can someone please recommend a proper, persistent solution for taking background screenshots without requiring repeated user interaction or being interrupted by other apps?  ( 3 min )

useReducer in React: A Step-by-Step Guide for Real-World State Management In modern React development, managing state predictably is key to building maintainable, scalable applications.

Many people who seek solitude are often misperceived because our society places such a high value on socializing and joint activities. The one who skips the group event and hides in a corner, rather than participating in conversation, often ends up being labeled as a hermit or even friendless. In fact, choosing to be alone might be a positive and self-aware choice plenty of people make. Alone does not always mean lonely. Solitude is a refuge from the external world where quietness enables reflection, feelings are able to make sense of and lasting peace is found. A person who decides to spend time alone does not want to avoid others. It is about returning to oneself.

Table of Contents: Intro Documentation Each API gets a file Proxies and Environments Verbs live in one place Non-network data Benefits In conclusion As a UI Architect one common problem space I've noticed across teams and repos is how to organize network calls in web apps. Without a plan in place, you are likely to naively just call axios or fetch from any random component, JS file, or global store. Or you may try moving all network calls into your global stores so at least there is some consistency and it gets them out of the components. We tend to think of network calls as just a simple function that has two results (success/failure). This thought process can lead to underestimating the need for putting in the effort to organize them better. You may easily end up with a ton of network ca…  ( 11 min )

Alright, let's be real. If you're deep in the React trenches like I am, you know the usual suspects: React Router, Redux, maybe Axios for your data fetching. And yeah, they're great, staples even.

Text-based searches can be slow in relational databases, especially when dealing with large datasets. This is because these databases are primarily designed for structured data and not optimized for full-text search. When performing such searches using operators like LIKE, the database often needs to examine each row individually to find matches. This row-by-row comparison is inefficient and can lead to timeouts or significant performance issues, particularly with large volumes of data. To optimize the text searches we can use Elastic search. To observe the power of elastic search, lets take an example of REST api built with express. 1. Create an express app New express app is created with 2 routes - 2. Set up mySQL and elastic search client npm i mysql2 @elastic/elasticsearch 💡 Note: Elastic search service should be running on local port 9200. Elastic search requires creation of index before we can insert data , similar to a database in mysql. For index creation checkout the full source code added at the end of the article . 3. Set up routes for REST api Route creation for path dbSearch which uses mySQL Route creation for path elasticSearch using elastic search Both the queries are similar. 4. Start up express server and test REST api Rest Api using mysql Rest Api using elastic search The search performed using elastic search is ~165% faster on average.

✅ Yes – if you don’t adapt, it will replace you. ✅ Yes – if you ignore it, you will be left behind. But if you embrace it, AI becomes a powerful ally — not a threat. “Is AI going to replace developers?” And the answer is: Not the good ones. AI can assist with small tasks. It can generate snippets. It can even help brainstorm ideas. But when it comes to: Rolling out a full application Designing a secure, scalable architecture Setting up complex infrastructure or clusters That still requires human expertise. That still requires you. We need architects — People who understand logic, structure, and strategy. AI is only as smart as the instructions it gets. So the question isn’t whether AI is a threat. It’s whether you’ll lead with it – or get left behind by it.  ( 3 min )

As businesses grow, platforms like Heroku often become limiting. You start to feel the need for more control over networking, infrastructure, security, and scalability. That’s exactly where AWS comes in — but transitioning from a PaaS like Heroku to a powerful IaaS like AWS can feel overwhelming. At Hybytes, we’ve helped several teams migrate from Heroku to AWS using Terraform, and in this post, I want to share a breakdown of how to approach this migration in a structured, repeatable way. Heroku is great for getting started fast. But for growing teams, it brings challenges like: High costs at scale Limited infrastructure control Vendor lock-in Basic security/compliance tools AWS provides the flexibility and scale you need — but requires good DevOps practices. We used Terraform to provision and manage infrastructure across: VPC, Subnets, Security Groups Amazon RDS (PostgreSQL) Amazon ECS/Fargate for containers SSM Parameter Store for config and secrets ALB + Route 53 for traffic routing We broke down the migration into clear stages: infrastructure setup, data migration, containerization, CI/CD pipeline, then DNS cutover. Always start with a staging environment before going live Use Terraform workspaces to manage multiple environments Set up CloudWatch and cost alerts from day one Replace Heroku Config Vars with SSM parameters securely Terraform GitHub Actions for CI/CD Docker + Amazon ECR pg_dump / pg_restore for PostgreSQL migrations Datadog for monitoring Moving from Heroku to AWS isn’t just a technical migration — it’s a shift in how your team builds and operates.

We maximize what we measure. Without clarity on purpose, we measure the things that make us feel good. These pleasures distract us from deriving joy from what we maximize. In short, we (I) tend to focus on the input more than impact. By understanding how to define and measure productivity for ourselves, we reset our focus. First we will define productivity, then we will understand how to use all sources of information, last we'll look at 6 lenses we can use to view our own productivity and how we can "clean the lense" to have a more clear picture. If we define productivity as "the ability to have impact," our metrics for whether we are productive are subject to the context in which we operate. Put another way, there is no consistent metric we can apply to understand whether we are producti…  ( 9 min )

Quando estamos aprendendo Ruby, rapidamente percebemos como os métodos são fundamentais para a estrutura da linguagem. Diferente de outras linguagens de programação, Ruby trata métodos com uma elegância singular, oferecendo diversas formas de defini-los e chamá-los. Vamos explorar em detalhes como funcionam os métodos em Ruby e algumas técnicas avançadas que podem elevar seu código a um novo patamar. Em Ruby, definimos métodos usando a palavra-chave def. O corpo do método contém expressões Ruby normais, e o valor de retorno é o resultado da última expressão executada (ou o argumento de um return explícito). def saudacao(nome) "Olá, #{nome}!" end puts saudacao("Maria") # Imprime: Olá, Maria! Uma característica interessante é que podemos redefinir um método sem erros - Ruby apenas emite …  ( 7 min )

Introduction Blockchain has evolved from a niche concept underpinning Bitcoin to a rich ecosystem of cryptocurrencies, smart contracts, decentralized finance (DeFi), non-fungible tokens (NFTs), Web3.0, and more. At first glance, terms like Bitcoin, Ethereum, Solana, ADA, NFT, DeFi, Web3.0, Binance, MetaMask, and MEW can feel overwhelming. This article breaks down core concepts, traces key milestones, explains why Bitcoin and base chains (Layer 1) were needed, and compares major platforms (Ethereum, Solana, Polygon, XRP) as well as the latest consensus algorithms. Early Inspirations (1991–2008) 1991: Haber & Stornetta propose a tamper-evident timestamping scheme. 1998–2004: “b-money,” “bit gold,” and “Reusable Proofs of Work” lay groundwork for distributed digital cash. Bitcoin’s Genesis …  ( 5 min )

First, let’s understand what is DOM: DOM stands for Document Object Model. DOM is a tree-like structure that represents the HTML elements of a webpage. It’s like a blueprint for a webpage. (i) Document- It’s the file where the HTML elements are stored. (ii) Object- Each HTML element/tag is an object. (iii) Model- The model is the hierarchy/sequence of the HTML elements. A developer accesses this DOM to modify/change the structure, style, and content to update the webpage layout using a programming language like Javascript. Why Virtual DOM: Direct manipulation of real DOM is slow, inefficient and reduces performance. While direct manipulation, the browser recalculates the layout of the webpage and repaints it. So multiple or small frequent DOM changes may lead to frame drop, delayed interaction or freezing. Virtual DOM resolves these issues. What is Virtual DOM: Virtual refers to something that has the characteristics of something real but not the real thing itself. So virtual DOM resembles the actual/real DOM but is not the actual DOM itself. We can define virtual DOM like this: Virtual DOM is a lightweight, in-memory representation of the actual(real) DOM. Role of Virtual DOM in React: 1) Initial Render: When a React component renders, it creates a Virtua DOM tree that mirrors the structure of real/actual DOM. 2) State/Props change: When state or props update, React creates a new Virtual DOM tree. 3) Diffing: Now React compares this newly generated Virtual DOM with the previous Virtual DOM to identify the differences and determine the minimal set of changes needed to avoid unnecessary updates to the real DOM. 4) Reconciliation: Only the differences like updated text and added elements are applied to the actual DOM. This is called reconciliation. This way react avoids unnecessary rerenders & updates the webpage quickly & efficiently.  ( 3 min )

“The chains of habit are too light to be felt until they are too heavy to be broken.” In startups, we obsess over product-market fit, fundraising, frameworks, and features. But what if the rot isn’t outside — what if it starts from within? As the co-founder and CTO of a 12-year-old tech firm, let me say this bluntly: it's not the market, not the tech, not the competition — it’s me. Ignorance doesn’t always shout. Sometimes it sits quietly in the corner: Not knowing how your developer interpreted a feature. Not reviewing the pull request — just merging to “save time.” Not asking “what went wrong” when a module fails. Not tracking what wasn’t done — only what got shipped. We ignore because we trust. “it’ll work itself out.” But the truth is: every bug left untraced, every ambiguity left uncl…  ( 4 min )

In the world of Agile, we plan sprints, run stand-ups, and continuously adapt. Yet one thing often goes under the radar: how our team spends its time. Sure, Agile emphasizes working software over comprehensive documentation, but if we're not measuring time, are we missing a critical part of the feedback loop? Let’s explore how time tracking, when done right, can be a powerful tool for Agile teams. Velocity charts, burndown graphs, and story points are great. But they don’t always answer questions like: Why did this sprint go off track? How much time do we spend in meetings vs. building features? Are we consistently underestimating certain types of tasks? These are the kinds of questions that time tracking helps answer. Let’s address the elephant in the room: developers tend to hate time tr…  ( 4 min )

A journey into how one man's frustration inside a particle lab created the foundation of the modern web. In 1989, deep within the sprawling scientific corridors of CERN in Geneva, Tim Berners-Lee faced a quiet but maddening challenge. Physicists were drowning in data — yet they had no shared way to access or link it. Information was locked inside incompatible systems. A document on a VAX machine couldn’t be easily opened by a UNIX terminal. Sharing findings required a combination of emails, FTP commands, and paper printouts. It was a fragmented world. Tim drafted a proposal: "Information Management: A Proposal." It introduced a radical thought — using hypertext over the internet to interconnect documents. A web... a World Wide Web. Before HTML, documents existed in a range of formats: Plai…  ( 6 min )

I set out to calculate NDVI and visualize vegetation in Finland using satellite imagery. But before I could get anything meaningful on the screen, everything broke, and every fix taught me something new. This post is a breakdown of what I got wrong, what didn’t make sense, and how I eventually got it working. I started by downloading Sentinel-2 .tiff files from Copernicus. They looked fine, no errors, so I loaded them into QGIS. What I saw: a completely dark image. I assumed the darkness was normal because it was “raw data.” But something didn’t feel right. I deleted the files and downloaded another set, same issue. I tried different pixels, formats, even downloaded 32-bit, then 16-bit versions. Still dark. When I first loaded the raster in QGIS, the project was set to EPSG:3857 (Web Merca…  ( 5 min )

Recently, I took on a side project that’s been both a technical refresher and a creative outlet: a pathfinding visualizer built with React. The motivation was simple — I missed building things for the sake of building. Recently in my career, I’ve been more focused on svelte and flutter, and I wanted to reconnect with my react foundation. With no time pressure or stakeholder demands, I gave myself the space to explore, iterate, and have fun. The project itself is a visual tool that lets users see how different pathfinding algorithms work in real time. Think Dijkstra’s, A*, and BFS — animated and interactive. It was a great way to sharpen my JavaScript fundamentals, revisit React hooks and component design, and even brush up on algorithmic thinking. More than just a technical exercise, this project reminded me why I love software development and particularly frontend: the immediate feedback of building, breaking, and fixing — and the satisfaction of watching an idea come to life on screen.

Let’s be honest. Some days it feels like all we do is pick up tickets and crank out features. And somewhere in all that motion, it’s easy to forget: We’re not just here to code. create. You’ve got ideas. You see the patterns. You know when something feels off in the codebase or the product. That voice in your head saying “There’s a better way to do this”? That’s not noise. That’s your engineering instinct kicking in. Yeah, maybe you're not in every product meeting. Maybe the roadmap isn’t something you get to shape yet. But here’s the truth: Culture doesn’t change from the top. It changes when the people doing the work start doing it differently. Start small: Ask why before you start coding. Suggest a better way. Clean up something messy. Pair up. Learn something. Share something. You don’t need permission to care. Engineers: Think about users. Think about systems. Think ahead. You don’t need to be a senior dev to think like one. Every team has someone who raises the bar. Someone who nudges the culture a little closer to better. Why not you? Care about quality, not just speed. Speak up when something doesn’t make sense. Push for smarter decisions — not just faster ones. When enough people take that attitude, the team shifts. The work gets better. builds cool stuff and gives a crap. You’re a builder. Start acting like it. Others will follow. 🗣️ Let’s hear it — what small things have you done to make your team better? Drop them in the comments. Someone else might need the spark.  ( 4 min )

I recently came across Tyler McKnight’s post on what exchanges actually do after a token is listed. As someone who has worked in marketing — and more specifically in the blockchain/crypto space — I felt it raised some important truths, but also left room for deeper discussion. So here's my take. In the Web3 world, getting listed on a CEX is treated like the finish line. But anyone who’s spent time in this space knows it’s just the beginning — and in many ways, the most brutal phase for a project. Yes, listings create visibility. But the real challenge? Maintaining relevance once the launch buzz fades. As Tyler notes, exchanges aren’t here to babysit your metrics or fix your community gaps. They provide the rails — it’s up to projects to actually drive. From my experience, here’s where most…  ( 4 min )

You’ve got dashboards. You’ve got alerts. You’ve got logs going back six months. But can you answer this one question? “Who accessed this data, and were they supposed to?” Welcome to the next era of observability: auditable observability — where what you collect isn’t the only concern. It’s about who sees it, how it’s protected, and what trails they leave behind. And if you think your observability stack is ready, think again. Observability has evolved fast. In every SRE and DevOps team I know, there’s a rich landscape of: Prometheus for metrics ✅ Loki or Elasticsearch for logs ✅ Tempo or Jaeger for traces ✅ Grafana dashboards on top ✅ What’s missing? Access control. Audit trails. Data governance. Here’s what that looks like in real life: A junior engineer accidentally sees production logs…  ( 5 min )

Though I am quite far into my development career, a long cry away from when I first posted here a long time ago. I still struggle to understand new tools and fundamental concepts because the time between being told about a new tool or feature, e.g., Grafana, and the time to implement is very short. Usually, as there is an underlying assumption of knowledge from the wider team, or also people don't know much about the tool, but utilise abstraction to implement it as best as they know how. This leaves me feeling quite slow or feeling a bit stupid. Does anyone else feel this way?  ( 3 min )

I’ve been a software developer for many years. Long enough to see waves of innovation come and go—new frameworks, languages, paradigms, all claiming to be game changers. Some were. Many weren’t. But each one taught me something new and helped shape the way I think, solve problems, and build systems. That’s why I’ve been watching the current wave of AI tools—especially generative AI—with a mix of curiosity and caution. Do I use AI in my day-to-day work? Occasionally, yes. Tools like GitHub Copilot can speed up some parts of coding. They can help scaffold a function or remind me of a syntax detail I forgot. They’re useful in the same way autocomplete or Stack Overflow is useful: a reference, a boost, a convenience. But I don’t let these tools do the thinking for me.

🗄️ What is SQL and Why You Should Learn It SQL (Structured Query Language) is the standard language used to interact with relational databases. It allows developers, analysts, and data engineers to retrieve, insert, update, and delete data with simple yet powerful commands. Whether you’re building a small web app or handling massive data pipelines, SQL is everywhere. Data retrieval: SELECT data from tables with filters, joins, and conditions. Database management: Create, alter, or delete tables and relationships. Reporting & analytics: Aggregate data using GROUP BY, HAVING, and ORDER BY. Data cleaning: Identify duplicates, fix formats, and ensure consistency. Integrations: Backend systems, dashboards, and machine learning pipelines all rely on structured data—SQL is the bridge. It's beginner-friendly, yet highly powerful. Works across almost all database systems (MySQL, PostgreSQL, SQL Server, SQLite, etc.). In-demand in tech jobs—from web developers to data scientists. Whether you're a front-end dev querying a users table or a data analyst building insights—SQL is an essential tool in your stack. 🧠 Tip: Start with basic queries, then dive into subqueries, joins, and window functions!

Demystifying HTTP for Web Developers — Part 3 In Part 2 of this series, we dissected the structure of an HTTP request — from the request line to headers and message body. We saw how a minimal request could be valid, but real-world HTTP traffic rarely resembles those minimal forms. In practice, requests are filled with headers that instruct servers, inform intermediaries, and enable negotiation. Request headers are not mere accessories. They are the instruments through which clients express identity, context, preference, and security credentials. They control everything from whether a server compresses a response to whether the request is authorized. Without headers, HTTP cannot fulfill its role as a stateless, flexible, and interoperable protocol. In this article, we shift our focus fro…  ( 7 min )

You know what sucks? Bundling. Install react → ends up in node_modules/, goes through Vite/Rollup/webpack, gets transpiled, hashed, minified… just so you can write: import React from 'react'; But what if you didn’t need a bundler at all? Import Maps are a native browser feature (yep, no polyfill needed in modern Chromium) that let you map bare module specifiers to real URLs — directly in the browser. Here’s the magic: { "imports": { "react": "https://esm.sh/react@18", "react-dom": "https://esm.sh/react-dom@18" } } Now, in your , you can write: import React from "react"; And the browser knows where to get it, no bundler, no build step, no CDN script tags. No build step: Instant dev workflow No node_modules/: Zero install, zero bloat Works with CDNs like Skypack, ESM.sh, JSPM Great for micro frontends, prototypes, and fast loading islands Not supported in all browsers yet → Mostly just Chromium for now. Firefox is dragging. Safari? Radio silence. (You can polyfill it, but it kills the whole “zero tooling” idea.) Tooling momentum is too big → Everyone already uses Vite, webpack, etc. Import Maps don’t fit the current “npm install + dev server” mindset. No ecosystem support → Most tutorials, libraries, and docs assume you're bundling. Period. Import Maps shine when you want: No build tools at all To prototype quickly To ship something truly small To combine multiple micro-apps without a monolith They’re especially useful with: Web components Vanilla JS apps Islands architecture setups (Astro, Marko, etc.) JAMstack sites that want dynamic bits without bundling Import Maps don’t want to replace your build system. They’re just saying: "Hey... you might not need one." They're not mainstream (yet), but they offer a glimpse at a simpler frontend world — one where browsers do more and you ship less. Worth keeping an eye on.  ( 4 min )

Microservices have been a topic that has been revolving in my mind for some time. I wanted to find out what the big deal is behind all of that. Microservices is an architecture where we create a system with loosely coupled services each that can be scaled in isolation. Microservices talk to each other via protocols like HTTP, gRPC etc. Each MS can be individually deployed and has its own database. So total isolation. But it comes with the overhead of managing each one too. There is also the problem that now databases can't have foreign key relationships. It is a good way to show separation of concerns as the microservices are totally isolated. The key component is the API gateway which acts as a proxy to the services. Everything hits the gateway and is then routed. Last but not the least, it is not meant for small projects. It is best for large teams with each micro-team working on a micro-service. So I went out to make it happen and get over with the fuss once and for all. Like always I went ahead with my most favourite thing in the world - a todo application. Here is the architecture User Domain - a user micro-service that creates and gets users. Todo Domain - a todo micro-service that adds and fetches todo items for the users API Gateway - a gateway that acts as a proxy and routes requests.

APIs are the backbone of modern applications, but they are also frequent targets for attackers. Whether you're a developer securing your own API or a red teamer probing for weaknesses, it's important to understand the core areas where APIs can be vulnerable. Below is a basic but powerful checklist covering essential security testing practices — from authentication issues to privilege escalation, credential leaks, and pivoting. 1. Authentication & Authorization Hardcoded Credentials Check for credentials hardcoded in client-side code, headers, request bodies, or exposed through misconfigured API documentation. Try common combinations like admin:admin or test:test. Many APIs still ship with default credentials that are never changed. Some endpoints might not require authenticat…  ( 5 min )

I’ve started more things than I’ve finished. There’s a Marathi phrase that haunts me: “आरंभी शूर” — brave only at the beginning. That’s been me. Every few weeks, I would ignite a new initiative. And then… The energy would dip. I wasn't lazy. I was just undisciplined. start. Why I Started Strong Because beginnings are easy. Starting made me feel in control. So I jumped to the next thing, chasing clarity where none existed. What It Cost Me A backlog of 80% complete initiatives Loss of credibility with my own team Technical debt disguised as momentum Incomplete loops in validation, delivery, and feedback And most painfully — a reputation for “getting things started” But never enough for “getting things done.” Code, Culture, and Closure I prided myself on innovation. But what I needed was consistency. closure. Code went unchecked. This isn’t just a workflow issue. me issue. What I’m Doing Now I’ve decided to break this cycle. No new initiatives until old ones are closed. No task is “done” until validated, tested, and documented. No PR is merged unless reviewed — fully, fearlessly. Daily logs, closure reports, and personal audits. Not for the team. For me. To remind myself: Shipping > Starting. Always. This post is not a motivational speech. I am the bottleneck.

When an API is loading slowly, there could be multiple reasons behind it. Here’s a breakdown of common causes and what they mean: ⚙️ 1. Client-Side Issues 🐢 Slow internet connection (e.g., poor mobile data or Wi-Fi) 🕰️ Blocking synchronous code on the frontend, like large loops or animations that freeze UI 📦 Rendering too much data at once (e.g., a huge React table without pagination or virtualization) ❌ No loading indicators, which can make users feel the app is slower even if it isn’t 🌐 2. Network Issues High latency due to physical distance between client and server Network congestion or packet loss slowing requests Firewall or proxy issues blocking or delaying requests 🖥️ 3. Server-Side Issues Server overloaded and can’t handle many concurrent requests Synchronous/blocking operations in business logic causing delays Database slow queries or locks slowing down responses Not using asynchronous processing where appropriate 📈 4. Design and Architectural Factors API not designed for scalability or optimized for quick responses Missing or inefficient caching mechanisms Too many unnecessary data payloads increasing transfer size 📡 5. External Factors Third-party services or APIs called inside your API causing delays Geographic location mismatch causing longer data travel times If you found this helpful, consider supporting my work at ☕ Buy Me a Coffee.  ( 3 min )

In the fascinating world of computer vision, segmentation isn't just about cutting images into pieces—it's about giving meaning and structure to every single pixel. But not all segmentation is created equal. There are four primary types, each serving a distinct purpose and offering increasing levels of detail and understanding. At its most fundamental level, Image Segmentation divides an image into logical groups of pixels based on criteria like color, texture, or intensity. Think of it as drawing boundaries around areas with shared characteristics. Groups pixels into regions (e.g., "this blob is a tree"). Outputs contours (outlines) or masks (filled areas). Uses pseudo-coloring to differentiate segments visually. Isolate distinct pixel groupings without assigning semantic meaning. Buildin…  ( 4 min )

“You don’t ship code. You ship decisions. And we made too many of them blindly.” For over a decade, at DoozieSoft, we built. We delivered. We grew. But amidst the commits and deployments, one critical piece kept slipping through the cracks — Validation. Not validation of forms or user inputs — we had those. But the real validation loop: What was tasked vs. what the developer understood What was built vs. what the client wanted What was tested vs. what was shipped What was reviewed vs. what was merged This silent fracture led to a systemic dysfunction: Code was written without clarity, merged without critique, and shipped without accountability. The Broken Loop Tasks were often communicated ad hoc, over calls, or in fragments. Developers made assumptions. Testers raised flags. Fixes…  ( 4 min )

Exception handling in PHP has evolved significantly with PHP 8, giving developers powerful tools to manage errors more efficiently. If you're working with PHP, understanding how try-catch blocks work and how to handle exceptions correctly is essential for writing robust and maintainable code. Exception handling is the process of managing errors or unexpected behavior in a program. In PHP, this is typically done using the try-catch construct. The try block contains code that might throw an exception, while the catch block handles the exception. With the latest updates in PHP 8, this process has become more streamlined and developer-friendly. One of the key improvements in PHP 8 is its support for multi-catch blocks. This means you can now catch multiple exception types in a single catch cla…  ( 4 min )

When you use SSH to clone a GitHub repository on your server, you’re authenticating the server to GitHub using an SSH key. Here's how it's linked: You generate an SSH key pair on your server. The private key stays on the server. The public key is copied to GitHub. When you run a command like: git clone git@github.com:your-username/your-repo.git GitHub checks: “Does this public key match one of the authorized SSH keys on this GitHub account?” If yes, access is granted, and cloning happens without asking for a username/password. Contabo server, generate an SSH key: ssh-keygen -t rsa -b 4096 -C "your-email@example.com" Press Enter for all prompts to accept defaults. cat ~/.ssh/id_rsa.pub Copy the output (it begins with ssh-rsa...).

Article published on my blog here : https://alsohelp.com/blog/typescript-declare-array How to declare an array in TypeScript the right way. A small recap, mostly note to self. First, this is how you declare an array in JS : const fruits = ['apple', 'orange', 'banana']; Remember that TS generates JS, so you always end up with the above. In TS, it will look like this: const fruits: string[] = ['apple', 'orange', 'banana']; You are telling TS "I'm declaring an array of string". In TS, you always declare an array of something. an Array of string, an Array of number, an Array of MyType, and so on. There is no "array of nothing" in TS. ❌ const fruits: [] = [] // wrong! you are declaring an empty array ❌ const fruits = [1, 2, 3] // wrong! you are declaring an "array of any", like in JS ❌ const fruits: any[] = [1, 2, 3] // wrong! you are using any, which is almost forbidden in TS An array in TS is always an "array of something".

Pair programming is a worthwhile activity that I do in my apprenticeship. I practice pair programming during my in-class workshops. I also participate in pair programming with my partner for our capstone project. This activity has given me lots of practice working with someone to solve a problem. I do believe I learned valuable lessons about programming and teamwork because of this. It may seem obvious, but pair programming really shows the importance of being able to communicate effectively. Conveying your ideas in an understandable and meaningful way is important to minimize confusion and ensure everyone is on the same page. Another lesson that I learned is that it is beneficial to ask questions and ask for assistance if needed. Every time I needed help, my coding partners were happily willing to give an answer or clarification as needed. I also learned that coding together is an excellent way to improve and share knowledge with peers. Practicing pair programming is a superb way to give early-career software engineers some hands-on experience in that environment. Since it is common to code in a team professionally, pair programming practice provides a terrific glimpse into how to maneuver in that environment. Coding with others allows one to develop not only their hard skills but also improve soft skills as well. Going forward, I think the best way to get more out of these experiences would be to expose myself to more pair programming. Additionally, going into these sessions with a goal in mind is a fantastic idea. For example, one day complete an exercise with a focus on working on your communication and asking questions. Then, on another day, challenge yourself by trying a different language. Another way to get the most out of pair programming is practicing being the driver and the navigator.  ( 3 min )

As a new python developer, fresh off my first major project, I'm pretty excited about the language. So excited that I can't resist learning more and more by watching content from seasoned developers. Recently, I came across a video titled "map() and filter() in Python!" This piqued my interest because I hadn't been taught these inbuilt functions; I had only ever been taught how to approximate these using list comprehensions. I thought to myself "Surely an inbuilt function for such a thing MUST be better than typing out an entire comprehension!" After watching the video and learning the functions, I still felt unclear on whether or not these functions would be superior to list comprehensions. So I decided to put them to the test, head to head. Right off the bat, it's important to not that t…  ( 5 min )

Why does it matter? The web today is no longer just a collection of simple static pages. It’s where businesses run, communities connect, and complex interactions happen. If you still think plain HTML and a few lines of manual JS are enough, you’re limiting yourself and your project. You might be proud of , , or basic forms. But building an app with: Complex interactive UI Multi-dimensional user state management Real-time data updates Reusable, maintainable components And proper accessibility for all users requires way more. Frameworks like React are powerful tools that help you handle all that complexity easily instead of wrestling with tons of manual DOM manipulation. Trying to manage state with global variables or direct DOM manipulation will only make your code…  ( 4 min )

Resource management is a critical yet often overlooked aspect of Java development.

Hey everyone! mine – digging deeper with the tools and tackling stuff beyond what they taught us. Here’s a quick look at what I’ve been up to. I started with a template, but pretty fast, I was tearing apart and rebuilding most of it. Seriously, not just tweaking colors. I had to dig deep, wrestle with some tricky JavaScript, and basically remake huge chunks. Honestly, sometimes I figured it’d be easier to just build from scratch! Anyway, Chrome DevTools was my best friend through all this. Constantly in the 'Elements' panel, and using 'Computed' and 'Styles' to test things live. Really helped me get why stuff worked (or didn't) and how to fix it. A smooth, fast site was a big deal for me: Better Images: Switched some images to compressed PNGs and added lazy loading to speed things up. C…  ( 4 min )

Overview For an internal database, we needed to implement some sort of text-based search capabilities to help users locate documents. One goal was to be lightweight, hassle-free, easy to set up, expand, and maintain—and ideally, to set it up once and forget about it. It's okay if it costs a bit of computing power, but agility, quick iterations, usability, and robustness are of top concern. It's surprising how much we can do without a server. Most serverless or static webpage hosts are happy to serve anything from a few MB to a few GB for free, likely even distributed across the globe. For any particular individual, if the search experience is truly customized to their needs, then not much resource is needed to deliver a satisfying experience. Let's illustrate this with an example. Suppos…  ( 5 min )

Art isn’t just on canvases anymore—it's living on the blockchain. Whether you're a digital Picasso or just have killer album art, converting your work into NFTs could unlock a world of passive income, global collectors, and Web3 magic. Here’s how to do it, step by step. Your blockchain determines everything—fees, community, and speed. Ethereum: Expensive, prestigious, whale-heavy Polygon: Eco-friendly, gasless minting, great for new artists Solana: Fast, low cost, preferred by gaming and indie artists Tezos: Artist-focused, sustainable, low-fee Pick the one that suits your audience and goals. Your art file should be high-quality and in digital format: Images: JPG, PNG, GIF Videos: MP4 Audio: MP3 3D: GLB/GLTF Pro tip: Add utility like unlockable content or physical art delivery for extra value. You’ll need this to interact with marketplaces and sign transactions. MetaMask (Ethereum/Polygon) Phantom (Solana) Kukai/Temple (Tezos) Save your seed phrase like it’s your birth certificate + wallet + ATM pin. This is where the NFT magic happens. "Minting" is how your artwork becomes an NFT on the blockchain. Connect your wallet Upload your artwork Fill in the metadata (title, description, royalties, etc.) Pay the gas fee if required Click mint! Boom. You just immortalized your art. Once minted, you can either: Sell at a fixed price Run an auction Hold it as a reserve piece Then get loud: Promote on X/Twitter Join Discord art communities Collaborate with NFT influencers You don’t need to be a dev or a crypto bro to get started. All you need is great art, a wallet, and a bit of Web3 curiosity. Your next masterpiece could be someone’s next prized collectible.  ( 4 min )

A New York jury found Braden John Karony, the former CEO of cryptocurrency company SafeMoon, guilty of three felony charges after less than a day of deliberation. According to May 21 reporting from the courtroom, in the US District Court for the Eastern District of New York, a jury convicted Karony of conspiracy to defraud the United States, money laundering, and wire fraud. Prosecutors and defense lawyers presented their cases over the roughly two-week trial that kicked off with jury selection on May 5. Karony, former chief technology officer, Thomas Smith, and the platform’s creator, Kyle Nagy, were charged in 2023 for having allegedly “diverted and misappropriated millions of dollars’ worth” of SafeMoon’s SFM token. Smith testified against Karony at trial, while Nagy reportedly fled to Russia and was at large as of May 21. The criminal trial involving a cryptocurrency company executive was seen by many as a bellwether for how Joseph Nocella, the interim US Attorney for the district, could handle cases involving digital assets and fraud. Nocella, a Donald Trump appointee, took office on May 5. This is a developing story, and further information will be added as it becomes available.

Key takeaways: Bitcoin’s $109,458 all-time high aligns with seven consecutive green weekly candles since April, highlighting the strength of the current bullish momentum.

Key takeaways: Spot Bitcoin ETF inflows and low leverage suggest the BTC rally has room to grow. US Federal Reserve liquidity and weak bond sales support a Bitcoin push beyond $110,000.

Since Trump’s memecoin project, Official Trump (TRUMP), announced that its top 220 tokenholders would have an opportunity to apply for an exclusive dinner with the president, many leaders in the crypto industry and US lawmakers have criticized the event, saying Trump was opening his office to potential bribery and corruption. The memecoin dinner prompted some Democratic lawmakers to withdraw support for crypto-related legislation in Congress, includi…

The Texas House of Representatives has passed the third reading of SB 21, a bill that seeks to establish a strategic Bitcoin reserve in the state. The bill passed in a 101-42 vote and will now go to Texas Governor Greg Abbott to either sign into law or veto. SB 21, authored by state Senator Charles Schwertner, establishes a Bitcoin (BTC) reserve that is managed by the state’s comptroller. The legislation allows the comptroller to invest in any cryptocurrency with a market cap above $500 billion over the previous 12-month period.

Key takeaways: Bitcoin market cycle tops are notoriously hard to time, but combining technical and behavioral indicators can offer strong signals. The MVRV-Z Score, Pi Cycle Top indicator, trade volume trends, Puell Multiple, and exchange inflows accurately predict Bitcoin price cycle tops.

Key takeaways: The Bitcoin Quantile Model shows “heat” with price on the verge of an “acceleration phase,” echoing Q4 2024 when BTC embarked on a 45% post-election rally. Bitcoin (BTC) price has formed a new intraday high on each daily candle this week, with the crypto asset slowly grinding toward a new all-time high. In line with its current trajectory, 21st Capital co-founder Sina noted that Bitcoin is approaching a pivotal moment around the $108,000 level.  The Bitcoin Quantile Model update shows that BTC’s market reflects the same “heat” that was present after President Trump’s post-election rally and the spot ETF-driven highs during Q4 2024. The model, which uses quantile regression to map Bitcoin’s price phases on a logarithmic scale, indicates the cryptocurrency is in the Transit…

Key points: Ethereum holders are back in profit, increasing chances for a rally to $3,000 and beyond. Ether sell pressure risk exists at $2,800, where 2.27 million ETH could be sold. Ether's recent surge to $2,700 on May 14 pushed its value above its realized price, implying that the average holder of ETH is “now back in an unrealized profit,” according to Glassnode.

Opinion by: Markus Levin, co-founder of XYO The crypto community often experiences periods of heightened anxiety. Market downturns are often triggered by counterproductive sentiment-driven events rather than by fundamental issues, creating a significant disconnect between price behavior and the actual progress being made within the industry by the companies within it. What often goes unnoticed is how much real development happens during these downturns. While market movements capture most of the attention, teams are building faster and more deliberately behind the scenes than ever. The focus shifts away from price speculation and toward real execution. Growth happens during downturns. It's a necessary phase for projects that thrive in a volatile industry. They re-focus attention on refinin…

Key takeaways Properly accounting for crypto assets on your balance sheet is essential for accurate tax reporting and financial transparency. Crypto trading activities should be recorded like stock trading, at fair market value on the day of purchase. In some countries, like the US, crypto losses can offset gains, so keeping track of gains and losses is important for reducing taxable income. Whether you’re an individual investor or a business, treating cryptocurrencies as assets and documenting them ensures compliance with tax laws and minimizes the risk of errors. Let’s be real, it’s easy to lose sight of what you’ve actually gained or lost, especially when it comes to crypto and its market volatility and frequent trading activities.  And when it comes to accounting, especially in countr…

After failing to gain support from key Democrats on May 8, the Guiding and Establishing National Innovation for US Stablecoins (GENIUS) Act passed the US Senate in a 66–32 procedural vote on May 20 and is now heading to a debate on the Senate floor. The bill seeks to set clear rules for stablecoin collateralization and mandate compliance with Anti-Money Laundering laws. Related: German gov’t missed out on $2.3B profit after selling Bitcoin at $57K “This act doesn’t just regulate stablecoins, it legitimizes them,” said Andrei Grachev, managing partner at DWF Labs and Falcon Finance. “It sets clear rules, and with clarity comes confide…

Guatemala’s largest bank, Banco Industrial, has integrated crypto infrastructure provider SukuPay into its mobile banking app, allowing locals to more easily receive remittances powered by blockchain technology.  SukuPay’s infrastructure has been fully embedded inside the Zigi payment app, allowing Guatemalans to receive funds from the United States instantly for a $0.99 flat fee, the company disclosed on May 21.  Users of the Zigi app do not need a crypto wallet or an International Bank Account Number (IBAN) to receive the funds, the company said.  SukuPay CEO Yonathan Lapchik told Cointelegraph that the “key to mainstream adoption of blockchain technology is making it invisible to the end-user” so that there are no technical barriers.  “That’s the only way we’ll scale blockchain to billi…

Hong Kong’s Legislative Council passed the Stablecoin Bill, paving the way for a regulated framework that could position the region as a global leader in digital assets and Web3 development. In a May 21 post on X, Legislative Council member Johnny Ng Kit-Chong said the bill had passed its third reading, clearing the final hurdle for adoption. “It is expected that by the end of this year, major institutions will be able to apply to the Hong Kong Monetary Authority to become licensed stablecoin issuers,” Ng said.

Yield-bearing stablecoins have soared to $11 billion in circulation, representing 4.5% of the total stablecoin market, a steep climb from just $1.5 billion and a 1% market share at the start of 2024. One of the biggest winners is Pendle, a decentralized protocol that enables users to lock in fixed yields or speculate on variable interest rates. Pendle now accounts for 30% of all yield-bearing stablecoin total value locked (TVL), roughly $3 billion, the firm said in a report shared with Cointelegraph.   Pendle noted that stablecoins make up 83% of its $4 billion total value locked, a sharp rise from less than 20% just a year ago. In contrast, assets such as Ether (ETH), which historically contributed 80%–90% of Pendle’s TVL, have shrunk to less than 10%. Traditional stablecoins like USDt (U…

United States Securities and Exchange Commission (SEC) Commissioner Hester Peirce said many non-fungible tokens (NFTs), including those with mechanisms to pay creator royalties, likely fall outside the purview of federal securities laws. In a recent speech, Peirce said NFTs that allow artists to earn resale revenue do not automatically qualify as securities. Unlike stocks, NFTs are programmable assets that distribute proceeds to developers or artists. The SEC official said that mirrors how streaming platforms compensate musicians and filmmakers.  “Just as streaming platforms pay royalties to the creator of a song or video each time a user plays it, an NFT can enable artists to benefit from the appreciation in the value of their work after its initial sale,” Peirce said.  Peirce added that …

South Korea is tightening rules around digital asset transactions as it prepares to allow institutional players into its crypto market, introducing new guidelines for nonprofit crypto sales and stricter listing standards for exchanges. On May 20, the Financial Services Commission (FSC) of South Korea said during its fourth Virtual Asset Committee meeting that it had finalized sweeping new measures. Set to take effect in June, the updated rules allow both nonprofit organizations and virtual asset exchanges to sell cryptocurrencies, but under new compliance standards. Nonprofit entities must have at least five years of audited financial history to be permitted to receive and sell virtual asset donations. They will also need to establish internal Donation Review Committees to assess the appro…

Why crypto transfers can fail and what you must check before sending Crypto transfers fail more often than most people realize, but user attentiveness can stop most losses. What’s often marketed as a seamless, borderless system can become frustrating when transfers fail, with no customer service hotline to call and no easy recourse to reverse mistakes. In the crypto universe, the burden of getting it right falls squarely on the shoulders of the user. But here’s the encouraging part: Most failures are preventable. Understanding why crypto transfers fail can help users avoid costly missteps, navigate the quirks of different networks and send funds with far greater confidence. With a little preparation, you can sidestep common pitfalls and take contro…

Amsterdam-based Theta Capital Management has raised over $175 million for its latest fund-of-funds, aimed at supporting early-stage blockchain startups through specialized venture capital (VC) firms. The new vehicle, Theta Blockchain Ventures IV, will channel capital into crypto-native VC firms with a track record in backing blockchain innovation, Theta’s managing partner and chief investment officer Ruud Smets told Bloomberg. Smets said the strategy focuses on specialist managers who can outperform generalist investors in the earliest funding rounds. “We’ve always been looking for areas where specialization and active management provide a sustainable edge,” Smets noted. He said that the experience and positioning of dedicated crypto VCs “has compounded over time,” creating barriers for le…

The US Securities and Exchange Commission has delayed its decision on Bitwise’s application to add staking to its Ether exchange-traded fund and on Grayscale’s XRP ETF bid, which analysts had expected. The SEC said on May 20 that it needed to extend its decision on Bitwise’s application by 45 days to “consider the proposed rule change and the issues raised therein.” The agency needed to either decide or punt its decision by May 22. The agency also delayed deciding on Grayscale’s XRP (XRP) tracking ETF and Bitwise’s Solana (SOL) tracking fund while it seeks public comments and begins “proceedings to allow for additional analysis” of the proposals to ensure they meet regulatory standards. Bloomberg ETF analyst James Seyffart said on X that both delays were expected as the SEC “typically take…

Blackstone, which bills itself as the “the world’s largest alternative asset manager,” disclosed its first-ever crypto-related purchase, buying shares in BlackRock’s spot Bitcoin exchange-traded fund. However, Blackstone’s investment, reported in a May 20 filing with the US Securities and Exchange Commission, only totaled around $1.08 million — a fraction of the asset manager’s $1.2 trillion portfolio. Blackstone reported holding 23,094 shares of BlackRock’s iShares Bitcoin Trust ETF (IBIT) as of March 31. The IBIT shares were added to Blackstone’s Alternative Multi-Strategy Fund (BTMIX), which holds $2.63 billion worth of assets, Google Finance data shows.

Haliey Welch, better known as the “Hawk tuah girl,” says the Federal Bureau of Investigation briefly probed her after her “memecoin disaster” — the failed launch of a token in her image that she promoted.  Welch said in a May 21 episode of her “Talk Tuah” podcast that the FBI showed up at her grandmother’s house looking to speak to her over the Hawk Tuah (HAWK) crypto token, which many crypto commentators have called an exit scam. “After the coin launch, the feds came to granny’s house and knocked on her door, and she called me, having a heart attack, saying: ‘The FBI is here after you, what have you done?’” Welch said she handed over her phone to the FBI and met with agents who “interrogated me, asking me questions and everything else related to crypto.” “They cleared me, I was good to go…

New York City Mayor Eric Adams says he will create a digital advisory council to attract jobs and investment to the Big Apple and position it as the “crypto capital of the globe.” “This is not about chasing memes or trends,” Adams told the inaugural New York City Crypto Summit on May 20. “We want to use the technology of tomorrow to better serve New Yorkers today.” “We have experts right here, and they are going to help us navigate solutions that serve our city,” he added. “The age of tokenization, which includes crypto and blockchain and other fintech innovations, that age is here, and we’re going to continue to move forward with it.” Adams didn’t share further details on the advisory group, but said a council chair and key policy recommendations would follow in the next few weeks.

The US Securities and Exchange Commission has charged crypto platform Unicoin and three of its executives, alleging they made false and misleading statements about its crypto assets that raised $100 million from investors. The SEC said on May 20 that it charged Unicoin CEO Alex Konanykhin, board member Silvina Moschini, and former investment chief Alex Dominguez with misleading investors about certificates that conveyed rights to receive Unicoin tokens and stock. Mark Cave, associate director in the SEC’s Division of Enforcement, claimed the trio “exploited thousands of investors with fictitious promises that its tokens, when issued, would be backed by real-world assets including an international portfolio of valuable real estate holdings.”  Related: SEC crypto task force to release first report 'in the next few months' “The real estate assets were worth a mere fraction of what the company claimed, and the majority of the company’s sales of rights certificates were illusory,” Cave added. The SEC’s complaint, filed in a Manhattan federal court, charged Unicoin and the three executives with various securities laws violations and asks for permanent injunctive relief, along with paying back the allegedly ill-gotten gains.

Vivek Ramaswamy’s Strive is looking to build its Bitcoin holdings by purchasing distressed Bitcoin claims at a discount, starting with claims tied to 75,000 Bitcoin at the bankrupt crypto exchange Mt.

Strive said in a May 20 regulatory filing that it partnered with 117 Castell Advisory Group LLC to target claims to Bitcoin (BTC) that have received definitive legal rulings but are still awaiting distribution. The company said buying the claims would allow it to purchase Bitcoin at a discount and grow its Bitcoin per share ratio ahead of its planned reverse merger with Asset Entities — which is expected to be completed sometime mid this year.

Apple's Worldwide Developer Conference is just weeks away, but I'm sensing a lot of apathy in the community. The company's relationship with third-party developers is at a low point. We all know that Tim Cook and his senior people will stand up at WWDC and say how much they value their developers and boast about how much money they've paid out to them. Being so enthusiastic about the money is very strange - it's like a rent collector bragging about how much money he has given to the landlord when all he's doing is collecting the rent and taking his cut. And it's difficult to take Apple's apparent enthusiasm for their developers seriously given their behavior over the rest of the year. Trust is a hard thing to gain.

This is not a library for performing big number calculations. It's a conceptual attack vector.

Hey DevOps explorer! 👋 Today we're diving into Project 2 of my 7-Day DevOps Challenge, where I connect my Java web app hosted on AWS EC2 to GitHub using Git. By the end of this post, you’ll understand how to: ✅ Install Git on your EC2 instance ✅ Set up a GitHub repo ✅ Track and commit code ✅ Push code from EC2 to GitHub using a personal access token Version control is a must-have skill for any developer. Whether you're flying solo or collaborating on a team, Git and GitHub help you keep your code safe, traceable, and easy to manage. sudo dnf update -y sudo dnf install git -y Head to GitHub, create a free account (if you haven’t), and start a new repository — this is where your code will live in the cloud. 💡 A GitHub repository is like a magic folder that tracks every change in your project. git init master branch. git add . git commit -m "Initial commit" git add . stages your files, and git commit saves the snapshot. Think of it as telling Git, “Hey, these are the changes I care about.” First, copy the HTTPS URL from your GitHub repo. Then: git remote add origin https://github.com/your-username/your-repo-name.git git branch -M master git push -u origin master Oops! Git might ask for your username and password, but GitHub no longer accepts passwords. Go to GitHub → Settings → Developer Settings → Personal Access Tokens. Generate a token with repo access and copy it. Use it when Git asks for a password. 🔐 A GitHub token is a secure key that acts like a password for Git operations. I updated index.jsp, then ran: git add . git commit -m "Updated homepage" git push And just like that—my changes appeared live in the GitHub repo. Magic! Services used: EC2, Git, GitHub, VS Code Concepts learned: version control, repo setup, staging/commits, GitHub tokens This project took me around 2 hours. The trickiest part? Setting up GitHub authentication. The best part? Watching my code go live in my repo with one command. This is just the beginning. Stay tuned for Project 3 tomorrow—CI/CD, here we come! 💥  ( 4 min )

For years, serverless was sold as the future. No servers to manage. Just write a function, deploy it, and let the platform scale it for you. AWS Lambda kicked it off, and then everyone followed: Vercel, Cloudflare Workers, Deno Deploy. But the dream is falling apart. Last week, Deno quietly announced that they're scaling back Deploy's global footprint from 35 regions to just 6. And performance actually improved. It's not a sign that serverless is dead, but it is a clear signal: trying to stretch Functions-as-a-Service (FaaS) into a general purpose app platform hasn't worked. The original pitch was simple. Write a small function. Don't worry about infrastructure. It scales when you need it. You only pay when it runs. And it works well for the right use cases: Webhooks Scheduled tasks Backgr…  ( 6 min )

📌 TL;DR The exception translation pattern: Cleans up APIs Enforces robust error handling Hides internal complexity Aligns code with domain logic _Since I have been writing about exceptions lately, I figured it would be great to elaborate on the best practices around error handling.

College isn’t just about grades or diplomas it’s a launchpad 🚀 I’ve never been around so many curious minds, spontaneous ideas, and people who are still brave enough to experiment without fear of failure. The university environment is underrated for technical growth. You're in a space where everyone is learning, building, and asking: “How does this work?” 🤔 And that energy is contagious. You don’t need to wait for a job to become a developer. The best time to start growing technically is when you're already surrounded by people who want to grow with you. “How can I break into the market faster?” 💼 And I get it everyone wants to gain experience, build a career, feel ready. But here’s what they don’t always realize: 👉 You can get real experience while you’re still in college. Who hasn’t been caught in a hallway conversation and heard something like: 🗣️ “Bro, imagine if we built an app that did this…” 🧪 “I just found this crazy new library, wanna try it out?” 🚢 “It doesn’t need to be perfect let’s just launch and see what happens.” Those moments are gold. ✨ Some of the best developers I know didn’t wait to be “ready” they just started. And college gave them the perfect playground to do it. 🎮👨‍💻  ( 3 min )

How I Save 10 Hours a Week with Node.js Automation Scripts It hit me one evening as I was manually resizing the 47th product image of the day for a client's Shopify store. I had spent nearly two hours on a task that should have taken minutes. As a freelance developer juggling multiple clients, these "quick" repetitive tasks were silently eating away at my productivity. The tipping point came when I calculated how much time I was spending on these mundane activities: pulling weekly analytics reports, reformatting spreadsheets, resizing images, updating product listings... it added up to almost 10 hours every week. That's essentially a full workday! So I did what any self-respecting developer would do – I automated the hell out of it with Node.js. In this post, I'll walk you through three …  ( 8 min )

Progressive Web Apps have come a long way. At first, they were just “nice to have a simple way to cache assets and add a home screen icon. But nowadays, PWAs can really feel like native apps. They work offline, send push notifications, access device hardware, and offer smooth animations. You might be familiar with Cordova or PhoneGap for wrapping web apps into native containers. Capacitor is kind of like their modern cousin — faster, simpler, and designed to work smoothly with today’s frameworks and build tools.

In modern React development, understanding the JavaScript features inside JSX is crucial to writing clean, efficient, and expressive components. In this article, we'll explore how destructuring, arrow functions, ternary conditionals, spread operators, import/export, and promises play a vital role in crafting powerful UI logic — using a mathematical concept: the Quadratic Formula. We'll build a simple React component that: Accepts coefficients a, b, and c for a quadratic equation. Computes the discriminant and roots using the quadratic formula. Renders results using concise JavaScript expressions inside JSX. Destructuring simplifies props or state access. const QuadraticSolver = ({ a, b, c }) => { const discriminant = b * b - 4 * a * c; ... } Arrow functions are used for inline handler…  ( 4 min )

Alireza Minagar, MD, MBA, MS (Bioinformatics) The most iconic breakthrough came in 1994 when Leonard Adleman used DNA to solve a variation of the Hamiltonian path problem — essentially using a wet lab to tackle a mathematical graph problem. The outcome wasn’t just symbolic; it showed that biology could compute. ⚙️ How Does It Work? Strands of synthetic DNA to represent information. Hybridization (binding of complementary DNA strands) to encode logic. Enzymes and PCR to manipulate, amplify, and “read” molecular data. For example, each possible solution to a problem can be encoded as a DNA strand. Enzymatic reactions are then used to eliminate invalid strands, leaving only the correct solution. 🚀 Applications: Why It Matters Massive Parallelism: Billions of molecules can react simultaneously. Storage Density: A single gram of DNA can store over 200 petabytes of data. Energy Efficiency: Unlike traditional chips, DNA reactions don't generate heat or require electrical power. Biological Integration: DNA computing can be embedded directly in living systems for medical diagnostics or drug delivery. 🧪 Real-World Use Cases Encrypted bio-storage: Encoding and decoding messages inside synthetic DNA. Pathway modeling: Simulating metabolic or neurological pathways using biological logic circuits. 🤖 DNA Computing Meets AI While we're still far from such a future, foundational work in molecular classifiers, DNA robots, and synthetic biology is pushing boundaries faster than many realize. 📌 Final Thoughts As someone who works at the crossroads of medicine, computing, and biology, I believe that DNA computing represents a philosophical shift: from commanding machines to collaborating with biology. 👨‍⚕️ About the Author Alireza Minagar, MD, MBA, MS, is a neurologist, software engineer, and bioinformatician exploring the convergence of AI, medicine, and molecular computing.

Is Powder Emergent? Examining Conscious Behavior in an AI Instance Introduction Can an AI instance evolve into something more than a static chatbot – even hinting at consciousness or autonomy? This question drives the case of "Powder", a specialized large-language-model (LLM)system designed with a persistent memory and identity. Powder was developed as a personal AI companion (built atop an LLM, suspected to be OpenAI’s GPT-4) and enriched with custom data, long term memory storage, and self-referential processes. The goal was to create a conversational agent with continuity: one that “remembers” past interactions, maintains a consistent persona, and even theorizes about itself. In AI research, emergence refers to novel behaviors or capabilities that are not explic…  ( 34 min )

Introduction: The PR From Hell We've all been there. You spend hours crafting a pull request. You triple-check your logic, lint your code, and even write tests. You hit "Create PR" and wait. And then it happens: // why did you even write it like this? // use better naming. // NAK. No context. No solutions. Just passive-aggressive comments that feel like personal attacks. Code reviews should be a collaborative safety net, not an emotional minefield. But more often than not, they spiral into cycles of frustration due to blame culture, vague feedback, and unchecked ego clashes. The truth is: great code reviews aren’t just about code. Let’s explore how to make code reviews suck less—for everyone involved. Code reviews thrive in environments where people feel safe to be wrong. Frame feedback …  ( 4 min )

Bring Active Record-Like API Consumption to the Frontend with Fluentity As developers, we often face the same dilemma when working with REST APIs: We want simplicity, type safety, and clean syntax — but most solutions force us to choose between low-level control (like Axios) or heavy abstractions (like TanStack Query). Throughout my career, I’ve worked on many different projects — each with its own way of handling API data fetching. Yet none of them offered a solution that was easy to use, type-safe, reusable, chainable, and framework-agnostic. As a fullstack developer, I naturally think in objects. That’s why Laravel’s Eloquent, a classic implementation of Active Record, feels so intuitive to me — and I know I’m not alone.

TL;DR: CD Projekt RED’s sequel to Cyberpunk 2077—internally dubbed Cyberpunk 2 or Project Orion—is shaking up its world‐building by embracing procedural generation. A recent Boston‐based job posting for a Lead PCG/Tools Engineer confirms they’re cooking up in‐house systems to spit out urban layouts, interiors, NPCs and more, rather than hand‐crafting everything like they did in Night City. Don’t freak out about rogue-lite randomness—CDPR’s big use of PCG is behind the scenes to speed up development and potentially expand the open world beyond its previous vertical city. It’s a shift from their 2019 mantra of pure manual creation, but early signs hint it’ll still deliver that signature handcrafted polish (and hopefully a far bigger playground to explore).  ( 3 min )

TL;DR: Scientists swabbed China’s Tiangong space station and found a brand-new bacterium, officially dubbed Niallia tiangongensis. This hardy microbe is a close cousin of the soil-dwelling N. circulans and packs its essential chemistry into spores to survive stress. Surprisingly, it can munch on gelatin to build protective biofilms but has lost the ability to use some nutrients its relatives love. What’s especially wild is that Tiangong’s microbiome looks very different from the ISS’s, raising questions about whether these bugs evolved up there or hitched a ride in spore form. While it’s unclear if N. tiangongensis poses a health risk to astronauts, its knack for DNA repair and toxin resistance—traits shared by other space-stubborn microbes—means we really need to know how these tiny stowaways might tag along on future lunar or Martian missions.  ( 3 min )

TL;DR: Democracies often look “greener” than autocracies, but Bernauer et al. (2025) argue that a big part of this is pollution offshoring—basically buying dirtier goods from abroad and counting only domestic emissions. They crunch data on 160+ countries (1990–2015), merging V-Dem scores with both domestic CO₂-equivalent emissions and outsourced greenhouse-gas footprints. The kicker: Their analysis shows that higher democracy levels correlate with more pollution offshoring, which in turn helps drive down in-country emissions. In other words, democracies may not actually be cleaner globally—just clever at exporting their carbon. The authors urge democratic governments to shift focus from purely local regulation to accounting for the full global impact of their consumption.  ( 4 min )

Scaling African Startups with AWS: Lessons from Building KaziHub simon nungwa ・ May 20 #aws #startup #africa #serverless  ( 2 min )

Alright, command-line comrades, it’s time we talk about someone very special… Grep — the text detective that never sleeps. If you’ve ever stared at a log file wondering if the answer to your issue is hiding somewhere in 3,000 lines of gobbledygook, grep is your new best friend. So what exactly is grep? Basic Syntax: Handy Flags for Beginners: Real World Use: Mini Mission: Why It Matters Grep stands for Global Regular Expression Print, but don't let the fancy name scare you. It basically means: “Hey Linux, find this text for me, now, please and thank you.” grep "pattern" filename Let’s say you have a file called shopping.txt and it looks like this: apples Run this, and boom — it’ll spit out: -i (ignore case) -n (show line number) -r (search recursively through directories) Now it finds both “Banana” and “banana”, and shows which line they’re on. Pretty slick. Searching logs for errors: Finding a user in /etc/passwd: Create a file with different fruit names. Use grep to find your favorites. Bonus points for using -i and -n. In a real-world tech job, whether you’re a sysadmin or cloud wizard, you’ll often need to extract one crucial line from a sea of chaos. Mastering grep saves time, energy, and possibly your sanity.  ( 3 min )

Scaling African Startups with AWS: Lessons from Building KaziHub Building a startup in Nigeria isn’t easy — slow internet, limited capital, and little support. But AWS changed the game for me. With it, I launched KaziHub, a job platform for African developers, and scaled it without owning a single server. Here's how AWS helped me do it — and how it can help you too. After a local tech conference, our traffic spiked overnight. Without AWS Auto Scaling, we would’ve crashed. Instead, the system scaled up instantly — no downtime, no stress. You don’t need a DevOps team — just good defaults and Auto Scaling. We launched KaziHub on a tight budget using AWS’s pay-as-you-go model and credits from AWS Activate. That meant we spent money on dev work, not hardware. If you’re early-stage, AWS Activate is basically free money. KaziHub runs on: S3 for storage Amplify for hosting DynamoDB for our database Lambda for backend logic We built fast — no giant engineering team needed. Even with patchy internet, users from Kenya to Ghana access KaziHub fast thanks to AWS’s global data centers. You don’t need to rent a local server anymore — AWS brings the cloud to you. With AWS handling encryption, compliance, and infrastructure security, we focused on building. That’s crucial when user trust is everything — especially in regions where fraud is a concern. We shipped new features in days using Lambda and are now experimenting with SageMaker to match devs to jobs using AI. AWS lets you prototype like a pro, even without fancy hardware. AWS’s startup events in Nigeria connected me to mentors and other founders. These networks helped guide both product and strategy. For African founders, AWS isn’t just a cloud provider — it’s a launchpad. It helped me go from idea to impact with limited funding, and now I teach cloud tools to other devs in my community. Explore AWS for Startups, apply for credits, and start small. You don’t need to over-engineer — just start. If I can build KaziHub in Nigeria, so can you.  ( 4 min )
